MTD updates for v4.13-rc1:
General updates * Cleanups and additional flash support for "dataflash" driver * new driver for mchp23k256 SPI SRAM device * improve handling of MTDs without eraseblocks (i.e., MTD_NO_ERASE) * refactor and improve "sub-partition" handling with TRX partition parser; partitions can now be created as sub-partitions of another partition SPI NOR updates, from Cyrille Pitchen and Marek Vasut: * introduce support to the SPI 1-2-2 and 1-4-4 protocols. * introduce support to the Double Data Rate (DDR) mode. * introduce support to the Octo SPI protocols. * add support to new memory parts for Spansion, Macronix and Winbond. * add fixes for the Aspeed, STM32 and Cadence QSPI controler drivers. * clean up the st_spi_fsm driver. NAND updates, from Boris Brezillon: * addition of on-die ECC support to Micron driver * addition of helpers to help drivers choose most appropriate ECC settings * deletion of dead-code (cached programming and ->errstat() hook) * make sure drivers that do not support the SET/GET FEATURES command return ENOTSUPP use a dummy ->set/get_features implementation returning -ENOTSUPP (required for Micron on-die ECC) * change the semantic of ecc->write_page() for drivers setting the NAND_ECC_CUSTOM_PAGE_ACCESS flag * support exiting 'GET STATUS' command in default ->cmdfunc() implementations * change the prototype of ->setup_data_interface() A bunch of driver related changes: * various cleanup, fixes and improvements of the MTK driver * OMAP DT bindings fixes * support for ->setup_data_interface() in the fsmc driver * support for imx7 in the gpmi driver * finalization of the denali driver rework (thanks to Masahiro for the work he's done on this driver) * fix "bitflips in erased pages" handling in the ifc driver * addition of PM ops and dynamic timing configuration to the atmel driver -----BEGIN PGP SIGNATURE----- Version: GnuPG v1 iQIcBAABAgAGBQJZZ7bdAAoJEFySrpd9RFgtZvIP+wfo25Lkv2gFRIFhnoDnxDfu 1pLVL8HrgTYBcD3dmr9ghONq+bxh2SSz3gU20i/eWmOmKy1OwaGegSj88hYpGOpS 2bwWWlczMqkX+upHw0une3ZrTb6pjoyHKHr5I5GYoJPgG2Dw2D3joehRkvMDispD 9cEik9HkyliHXy/1mqFsToe5RwdqauLbKR/a2XZQo89gt8n8Rnlt91Q5QOZytC6r GLkuQzRAf4qVi4sgDb7zvFZW7KeyGTXTLDxKZGG9JETNjzcEJZMykAWxR9SwBCHa tL7HjyaU5d2rXo4ukZ4IplKn9Y+BneDeGomy44DcGP6RAyNDqVC/R5eFW+MtlbwY rm6SDxs9vCeUBrgIaJlVqDJxca/OR3ruHKILGbEfvIy/MmRQ4keBf357Dew8o4x/ wQw2dgznn3/vs5aqSz/E+erY22gdnaHtDApaefB/D0Kqi9fs2yVaAh3gGcXmloO9 yfRfzPugMRwI29gztMkgRWKWTCfHe2JN4hLDMVwO7Rt3ucQIbz642N/4JVMEpDcX gJcaSgXn/u6xRJnEX/2u+B6ERNqVvLZ8fbnfD0fkPkjLOISvfg38xti1qgoxs8z8 tm5lMI7VR9/MKIxCXT/6Z+actDV21j/oo0QInV3YMxHDPl5KBj+migsRtDzpGhna dmztYIMYqF9I29skWgXR =ReBr -----END PGP SIGNATURE----- Merge tag 'for-linus-20170713' of git://git.infradead.org/linux-mtd Pull MTD updates from Brian Norris: "General updates: - Cleanups and additional flash support for "dataflash" driver - new driver for mchp23k256 SPI SRAM device - improve handling of MTDs without eraseblocks (i.e., MTD_NO_ERASE) - refactor and improve "sub-partition" handling with TRX partition parser; partitions can now be created as sub-partitions of another partition SPINOR updates, from Cyrille Pitchen and Marek Vasut: - introduce support to the SPI 1-2-2 and 1-4-4 protocols. - introduce support to the Double Data Rate (DDR) mode. - introduce support to the Octo SPI protocols. - add support to new memory parts for Spansion, Macronix and Winbond. - add fixes for the Aspeed, STM32 and Cadence QSPI controler drivers. - clean up the st_spi_fsm driver.

Documentation: ABI: mtd: describe "offset" more precisely
So far Linux supported only two levels of MTD devices so we didn't need
a very precise description for this sysfs file. With commit

f2fs: introduce reserved_blocks in sysfs
In this patch, we add a new sysfs interface, with it, we can control number of reserved blocks in system which could not be used by user, it enable f2fs to let user to configure for adjusting over-provision ratio dynamically instead of changing it by mkfs. So we can expect it will help to reserve more free space for relieving GC in both filesystem and flash device.

Merge branch 'next' of git://git.kernel.org/pub/scm/linux/kernel/git/jmorris/linux-security
Pull security layer updates from James Morris: - a major update for AppArmor. From JJ: * several bug fixes and cleanups * the patch to add symlink support to securityfs that was floated on the list earlier and the apparmorfs changes that make use of securityfs symlinks * it introduces the domain labeling base code that Ubuntu has been carrying for several years, with several cleanups applied. And it converts the current mediation over to using the domain labeling base, which brings domain stacking support with it. This finally will bring the base upstream code in line with Ubuntu and provide a base to upstream the new feature work that Ubuntu carries. * This does _not_ contain any of the newer apparmor mediation features/controls (mount, signals, network, keys, ...) that Ubuntu is currently carrying, all of which will be RFC'd on top of this. - Notable also is the Infiniband work in SELinux, and the new file:map permission. From Paul: "While we're down to 21 patches for v4.13 (it was 31 for v4.12), the diffstat jumps up tremendously with over 2k of line changes. Almost all of these changes are the SELinux/IB work done by Daniel Jurgens; some other noteworthy changes include a NFS v4.2 labeling fix, a new file:map permission, and reporting of policy capabilities on policy load" There's also now genfscon labeling support for tracefs, which was lost in v4.1 with the separation from debugfs. - Smack incorporates a safer socket check in file_receive, and adds a cap_capable call in privilege check. - TPM as usual has a bunch of fixes and enhancements. - Multiple calls to security_add_hooks() can now be made for the same LSM, to allow LSMs to have hook declarations across multiple files. - IMA now supports different "ima_appraise=" modes (eg. log, fix) from the boot command line. * 'next' of git://git.kernel.org/pub/scm/linux/kernel/git/jmorris/linux-security: (126 commits) apparmor: put back designators in struct initialisers seccomp: Switch from atomic_t to recount_t seccomp: Adjust selftests to avoid double-join seccomp: Clean up core dump logic IMA: update IMA policy documentation to include pcr= option ima: Log the same audit cause whenever a file has no signature ima: Simplify policy_func_show. integrity: Small code improvements ima: fix get_binary_runtime_size() ima: use ima_parse_buf() to parse template data ima: use ima_parse_buf() to parse measurements headers ima: introduce ima_parse_buf() ima: Add cgroups2 to the defaults list ima: use memdup_user_nul ima: fix up #endif comments IMA: Correct Kconfig dependencies for hash selection ima: define is_ima_appraise_enabled() ima: define Kconfig IMA_APPRAISE_BOOTPARAM option ima: define a set of appraisal rules requiring file signatures ima: extend the "ima_policy" boot command line to support multiple policies ... |

usb: gadget: add f_uac1 variant based on a new u_audio api
This patch adds a new function 'f_uac1' (f_uac1 with virtual "ALSA card") that uses recently created u_audio API. Comparing to legacy f_uac1 function implementation it doesn't require any real Audio codec to be present on the device. In f_uac1 audio streams are simply sinked to and sourced from a virtual ALSA sound card created using u_audio API. Legacy f_uac1 approach is to write audio samples directly to existing ALSA sound card f_uac1 approach is more generic/flexible one - create an ALSA sound card that represents USB Audio function and allows to be used by userspace application that may choose to do whatever it wants with the data received from the USB Host and choose to provide whatever it wants as audio data to the USB Host. f_uac1 also has capture support (gadget->host) thanks to easy implementation via u_audio. By default, capture interface has 48000kHz/2ch configuration, same as playback channel has. f_uac1 descriptors naming convention uses f_uac2 driver naming convention that makes it more common and meaningful. Comparing to f_uac1_legacy, the f_uac1 doesn't have volume/mute functionality. This is because the f_uac1 volume/mute feature unit was dummy implementation since that driver creation (2009) and never had any real volume control or mute functionality, so there is no any difference here. Since f_uac1 functionality, exposed interface to userspace (virtual ALSA card), input parameters are so different comparing to f_uac1_legacy, that there is no any reason to keep them in the same file/module, and separate function was created. g_audio can be built using one of existing UAC functions (f_uac1, f_uac1_legacy or f_uac2) Signed-off-by: Ruslan Bilovol <ruslan.bilovol@gmail.com> Signed-off-by: Felipe Balbi <felipe.balbi@linux.intel.com> |

xen: add sysfs node for guest type
Currently there is no reliable user interface inside a Xen guest to determine its type (e.g. HVM, PV or PVH). Instead of letting user mode try to determine this by various rather hacky mechanisms (parsing of boot messages before they are gone, trying to make use of known subtle differences in behavior of some instructions), add a sysfs node /sys/hypervisor/guest_type to explicitly deliver this information as it is known to the kernel.

thunderbolt: Add support for host and device NVM firmware upgrade
Starting from Intel Falcon Ridge the NVM firmware can be upgraded by using DMA configuration based mailbox commands. If we detect that the host or device (device support starts from Intel Alpine Ridge) has the DMA configuration based mailbox we expose NVM information to the userspace as two separate Linux NVMem devices: nvm_active and nvm_non_active. The former is read-only portion of the active NVM which firmware upgrade tools can be use to find out suitable NVM image if the device identification strings are not enough. The latter is write-only portion where the new NVM image is to be written by the userspace. It is up to the userspace to find out right NVM image (the kernel does very minimal validation). The ICM firmware itself authenticates the new NVM firmware and fails the operation if it is not what is expected. We also expose two new sysfs files per each switch: nvm_version and nvm_authenticate which can be used to read the active NVM version and start the upgrade process. We also introduce safe mode which is the mode a switch goes when it does not have properly authenticated firmware. In this mode the switch only accepts a couple of commands including flashing a new NVM firmware image and triggering power cycle. This code is based on the work done by Amir Levy and Michael Jamet.

thunderbolt: Add support for Internal Connection Manager (ICM)
Starting from Intel Falcon Ridge the internal connection manager running on the Thunderbolt host controller has been supporting 4 security levels. One reason for this is to prevent DMA attacks and only allow connecting devices the user trusts. The internal connection manager (ICM) is the preferred way of connecting Thunderbolt devices over software only implementation typically used on Macs. The driver communicates with ICM using special Thunderbolt ring 0 (control channel) messages. In order to handle these messages we add support for the ICM messages to the control channel. The security levels are as follows: none - No security, all tunnels are created automatically user - User needs to approve the device before tunnels are created secure - User need to approve the device before tunnels are created. The device is sent a challenge on future connects to be able to verify it is actually the approved device. dponly - Only Display Port and USB tunnels can be created and those are created automatically. The security levels are typically configurable from the system BIOS and by default it is set to "user" on many systems. In this patch each Thunderbolt device will have either one or two new sysfs attributes: authorized and key. The latter appears for devices that support secure connect. In order to identify the device the user can read identication information, including UUID and name of the device from sysfs and based on that make a decision to authorize the device. The device is authorized by simply writing 1 to the "authorized" sysfs attribute. This is following the USB bus device authorization mechanism. The secure connect requires an additional challenge step (writing 2 to the "authorized" attribute) in future connects when the key has already been stored to the NVM of the device. Non-ICM systems (before Alpine Ridge) continue to use the existing functionality and the security level is set to none. For systems with Alpine Ridge, even on Apple hardware, we will use ICM. This code is based on the work done by Amir Levy and Michael Jamet.

thunderbolt: Convert switch to a device
Thunderbolt domain consists of switches that are connected to each other, forming a bus. This will convert each switch into a real Linux device structure and adds them to the domain. The advantage here is that we get all the goodies from the driver core, like reference counting and sysfs hierarchy for free. Also expose device identification information to the userspace via new sysfs attributes. In order to support internal connection manager (ICM) we separate switch configuration into its own function (tb_switch_configure()) which is only called by the existing native connection manager implementation used on Macs.

mux: minimal mux subsystem
Add a new minimalistic subsystem that handles multiplexer controllers. When multiplexers are used in various places in the kernel, and the same multiplexer controller can be used for several independent things, there should be one place to implement support for said multiplexer controller. A single multiplexer controller can also be used to control several parallel multiplexers, that are in turn used by different subsystems in the kernel, leading to a need to coordinate multiplexer accesses. The multiplexer subsystem handles this coordination.

kobject: support passing in variables for synthetic uevents
This patch makes it possible to pass additional arguments in addition to uevent action name when writing /sys/.../uevent attribute. These additional arguments are then inserted into generated synthetic uevent as additional environment variables. Before, we were not able to pass any additional uevent environment variables for synthetic uevents. This made it hard to identify such uevents properly in userspace to make proper distinction between genuine uevents originating from kernel and synthetic uevents triggered from userspace. Also, it was not possible to pass any additional information which would make it possible to optimize and change the way the synthetic uevents are processed back in userspace based on the originating environment of the triggering action in userspace. With the extra additional variables, we are able to pass through this extra information needed and also it makes it possible to synchronize with such synthetic uevents as they can be clearly identified back in userspace. The format for writing the uevent attribute is following: ACTION [UUID [KEY=VALUE ...] There's no change in how "ACTION" is recognized - it stays the same ("add", "change", "remove"). The "ACTION" is the only argument required to generate synthetic uevent, the rest of arguments, that this patch adds support for, are optional. The "UUID" is considered as transaction identifier so it's possible to use the same UUID value for one or more synthetic uevents in which case we logically group these uevents together for any userspace listeners. The "UUID" is expected to be in "xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx" format where "x" is a hex digit. The value appears in uevent as "SYNTH_UUID=xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx" environment variable. The "KEY=VALUE" pairs can contain alphanumeric characters only. It's possible to define zero or more more pairs - each pair is then delimited by a space character " ". Each pair appears in synthetic uevents as "SYNTH_ARG_KEY=VALUE" environment variable. That means the KEY name gains "SYNTH_ARG_" prefix to avoid possible collisions with existing variables. To pass the "KEY=VALUE" pairs, it's also required to pass in the "UUID" part for the synthetic uevent first. If "UUID" is not passed in, the generated synthetic uevent gains "SYNTH_UUID=0" environment variable automatically so it's possible to identify this situation in userspace when reading generated uevent and so we can still make a difference between genuine and synthetic uevents.

drivers/serial: Add driver for Aspeed virtual UART
This change adds a driver for the 16550-based Aspeed virtual UART device. We use a similar process to the of_serial driver for device probe, but expose some VUART-specific functions through sysfs too. The VUART is two UART 'front ends' connected by their FIFO (no actual serial line in between). One is on the BMC side (management controller) and one is on the host CPU side. This driver is for the BMC side. The sysfs files allow the BMC userspace, which owns the system configuration policy, to specify at what IO port and interrupt number the host side will appear to the host on the Host <-> BMC LPC bus. It could be different on a different system (though most of them use 3f8/4). OpenPOWER host firmware doesn't like it when the host-side of the VUART's FIFO is not drained. This driver only disables host TX discard mode when the port is in use. We set the VUART enabled bit when we bind to the device, and clear it on unbind. We don't want to do this on open/release, as the host may be using this bit to configure serial output modes, which is independent of whether the devices has been opened by BMC userspace.

USB patches for 4.12-rc1
Here is the big USB patchset for 4.12-rc1. Lots of good stuff here, after many many many attempts, the kernel finally has a working typeC interface, many thanks to the Heikki and Guenter and others who have taken the time to get this merged. It wasn't an easy path for them at all. There's also a staging driver that uses this new api, which is why it's coming in through this tree. Along with that, there's the usual huge number of changes for gadget drivers, xhci, and other stuff. Johan also finally refactored pretty much every driver that was looking at USB endpoints to do it in a common way, which will help prevent any "badly-formed" devices from causing problems in drivers. That too wasn't a simple task. All of these have been in linux-next for a while with no reported issues.

Pull livepatch updates from Jiri Kosina: - a per-task consistency model is being added for architectures that support reliable stack dumping (extending this, currently rather trivial set, is currently in the works). This extends the nature of the types of patches that can be applied by live patching infrastructure. The code stems from the design proposal made [1] back in November 2014. It's a hybrid of SUSE's kGraft and RH's kpatch, combining advantages of both: it uses kGraft's per-task consistency and syscall barrier switching combined with kpatch's stack trace switching. There are also a number of fallback options which make it quite flexible. Most of the heavy lifting done by Josh Poimboeuf with help from Miroslav Benes and Petr Mladek [1] https://lkml.kernel.org/r/20141107140458.GA21774@suse.cz - module load time patch optimization from Zhou Chengming - a few assorted small fixes * 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/jikos/livepatching: livepatch: add missing printk newlines livepatch: Cancel transition a safe way for immediate patches livepatch: Reduce the time of finding module symbols livepatch: make klp_mutex proper part of API livepatch: allow removal of a disabled patch livepatch: add /proc/<pid>/patch_state livepatch: change to a per-task consistency model livepatch: store function sizes livepatch: use kstrtobool() in enabled_store() livepatch: move patching functions into patch.c livepatch: remove unnecessary object loaded check livepatch: separate enabled and patched states livepatch/s390: add TIF_PATCH_PENDING thread flag livepatch/s390: reorganize TIF thread flag bits livepatch/powerpc: add TIF_PATCH_PENDING thread flag livepatch/x86: add TIF_PATCH_PENDING thread flag livepatch: create temporary klp_update_patch_state() stub x86/entry: define _TIF_ALLWORK_MASK flags explicitly stacktrace/x86: add function for detecting reliable stack traces |

PCI: Add sysfs sriov_drivers_autoprobe to control VF driver binding
Sometimes it is not desirable to bind SR-IOV VFs to drivers. This can save host side resource usage by VF instances that will be assigned to VMs. Add a new PCI sysfs interface "sriov_drivers_autoprobe" to control that from the PF. To modify it, echo 0/n/N (disable probe) or 1/y/Y (enable probe) to: /sys/bus/pci/devices/<DOMAIN:BUS:DEVICE.FUNCTION>/sriov_drivers_autoprobe Note that this must be done before enabling VFs. The change will not take effect if VFs are already enabled. Simply, one can disable VFs by setting sriov_numvfs to 0, choose whether to probe or not, and then re-enable the VFs by restoring sriov_numvfs.

ACPI / scan: Drop support for force_remove
/sys/firmware/acpi/hotplug/force_remove was presumably added to support auto offlining in the past. This is, however, inherently dangerous for some hotplugable resources like memory. The memory offlining fails when the memory is still in use and cannot be dropped or migrated. If we ignore the failure we are basically allowing for subtle memory corruption or a crash. We have actually noticed the later while hitting BUG() during the memory hotremove (remove_memory): ret = walk_memory_range(PFN_DOWN(start), PFN_UP(start + size - 1), NULL, check_memblock_offlined_cb); if (ret) BUG(); it took us quite non-trivial time realize that the customer had force_remove enabled. Even if the BUG was removed here and we could propagate the error up the call chain it wouldn't help at all because then we would hit a crash or a memory corruption later and harder to debug. So force_remove is unfixable for the memory hotremove. We haven't checked other hotplugable resources to be prone to a similar problems. Remove the force_remove functionality because it is not fixable currently. Keep the sysfs file and report an error if somebody tries to enable it. Encourage users to report about the missing functionality and work with them with an alternative solution.

usb: gadget: udc: renesas_usb3: add support for usb role swap
This patch adds support for usb role swap via sysfs "role". For example: 1) Connect a usb cable using 2 Salvator-X boards. - For A-Device, the cable is connected to CN11 (USB3.0 ch0). - For B-Device, the cable is connected to CN9 (USB2.0 ch0). 2) On A-Device, you input the following command: # echo peripheral > /sys/devices/platform/soc/ee020000.usb/role 3) On B-Device, you input the following command: # echo host > /sys/devices/platform/soc/ee080200.usb-phy/role Then, the A-Device acts as a peripheral and the B-Device acts as a host. Please note that A-Device must input the following command if you want the board to act as a host again. # echo host > /sys/devices/platform/soc/ee020000.usb/role Signed-off-by: Yoshihiro Shimoda <yoshihiro.shimoda.uh@renesas.com> Signed-off-by: Felipe Balbi <felipe.balbi@linux.intel.com> |

livepatch: change to a per-task consistency model
Change livepatch to use a basic per-task consistency model. This is the foundation which will eventually enable us to patch those ~10% of security patches which change function or data semantics. This is the biggest remaining piece needed to make livepatch more generally useful. This code stems from the design proposal made by Vojtech [1] in November 2014. It's a hybrid of kGraft and kpatch: it uses kGraft's per-task consistency and syscall barrier switching combined with kpatch's stack trace switching. There are also a number of fallback options which make it quite flexible. Patches are applied on a per-task basis, when the task is deemed safe to switch over. When a patch is enabled, livepatch enters into a transition state where tasks are converging to the patched state. Usually this transition state can complete in a few seconds. The same sequence occurs when a patch is disabled, except the tasks converge from the patched state to the unpatched state. An interrupt handler inherits the patched state of the task it interrupts. The same is true for forked tasks: the child inherits the patched state of the parent. Livepatch uses several complementary approaches to determine when it's safe to patch tasks: 1. The first and most effective approach is stack checking of sleeping tasks. If no affected functions are on the stack of a given task, the task is patched. In most cases this will patch most or all of the tasks on the first try. Otherwise it'll keep trying periodically. This option is only available if the architecture has reliable stacks (HAVE_RELIABLE_STACKTRACE). 2. The second approach, if needed, is kernel exit switching. A task is switched when it returns to user space from a system call, a user space IRQ, or a signal. It's useful in the following cases: a) Patching I/O-bound user tasks which are sleeping on an affected function. In this case you have to send SIGSTOP and SIGCONT to force it to exit the kernel and be patched. b) Patching CPU-bound user tasks. If the task is highly CPU-bound then it will get patched the next time it gets interrupted by an IRQ. c) In the future it could be useful for applying patches for architectures which don't yet have HAVE_RELIABLE_STACKTRACE. In this case you would have to signal most of the tasks on the system. However this isn't supported yet because there's currently no way to patch kthreads without HAVE_RELIABLE_STACKTRACE. 3. For idle "swapper" tasks, since they don't ever exit the kernel, they instead have a klp_update_patch_state() call in the idle loop which allows them to be patched before the CPU enters the idle state. (Note there's not yet such an approach for kthreads.) All the above approaches may be skipped by setting the 'immediate' flag in the 'klp_patch' struct, which will disable per-task consistency and patch all tasks immediately. This can be useful if the patch doesn't change any function or data semantics. Note that, even with this flag set, it's possible that some tasks may still be running with an old version of the function, until that function returns. There's also an 'immediate' flag in the 'klp_func' struct which allows you to specify that certain functions in the patch can be applied without per-task consistency. This might be useful if you want to patch a common function like schedule(), and the function change doesn't need consistency but the rest of the patch does. For architectures which don't have HAVE_RELIABLE_STACKTRACE, the user must set patch->immediate which causes all tasks to be patched immediately. This option should be used with care, only when the patch doesn't change any function or data semantics. In the future, architectures which don't have HAVE_RELIABLE_STACKTRACE may be allowed to use per-task consistency if we can come up with another way to patch kthreads. The /sys/kernel/livepatch/<patch>/transition file shows whether a patch is in transition. Only a single patch (the topmost patch on the stack) can be in transition at a given time. A patch can remain in transition indefinitely, if any of the tasks are stuck in the initial patch state. A transition can be reversed and effectively canceled by writing the opposite value to the /sys/kernel/livepatch/<patch>/enabled file while the transition is in progress. Then all the tasks will attempt to converge back to the original patch state.

First set of IIO new device support, features and cleanup for the 4.12 cycle.
Quite a bit of outreachy activity here with a driver from a current intern and a number of cleanup patches as part of the next round. Getting a pull request in early this cycle as it's looking like another large cycle for IIO. New device support * adxl345 - initial device support. Note, once complete support is done the intent is to superceded the driver in input/misc. - bindings. - conversion from i2c direct calls to regmap and driver split. - spi support. * chromeos light and proximity. - new driver. * devantech srf04 ultrasonic ranger - new driver with device tree bindings. * hid temperature - new driver for environemntal temperature support from hid devices. * max30102 oximeter - new driver with device tree bindings. * st lsm6dsx - refactor and addition of device support for lsm6dsl and lsm6ds3h. Staging graduation * isl29028 including copyright notice update to reflect Brian's work. * lpc32xx_adc. * spear adc. It's not perfect and there are some datasheet disagreements, but it works and is good enough to graduate. New features * documentation - abi docs for in_proximity_sampling_frequency_available. - generalise counting direction ABI docs as a second driver is going to use them. * hid-sensor-prox - Add support for HID_USAGE_SENSOR_HUMAN_PRESENCE if used on a particular device. * isl29028 - runtime pm. * meson-saradc - switch from polling to interrupt mode and improved read_raw_sample function to avoid unnecessary loop. * tmp007 - interrupt and threshold event support. Cleanups and minor fixes * ad2s1210 - permissions to octal. * ad7192 - permissions to octal. - use BIT macro. * ad9832 - merge header definitions into source file. * ad9834 - merge header definitions into source file. * ade7753 - merge header definitions into source file. - cleanup include ordering. * |

zram: remove obsolete sysfs attrs
We had a deprecated_attr_warn() warning for 2 years and now the time has come and we finally can do the cleanup. The plan was as follows: : per-stat sysfs attributes are considered to be deprecated. : The basic strategy is: : -- the existing RW nodes will be downgraded to WO nodes (in linux 4.11) : -- deprecated RO sysfs nodes will eventually be removed (in linux 4.11) : : The list of deprecated attributes can be found here: : Documentation/ABI/obsolete/sysfs-block-zram : : Basically, every attribute that has its own read accessible sysfs : node (e.g. num_reads) *AND* is accessible via one of the stat files : (zram<id>/stat or zram<id>/io_stat or zram<id>/mm_stat) is considered : to be deprecated. The patch also removes `obsolete/sysfs-block-zram', clean ups `testing/sysfs-block-zram' and tweaks zram.txt files.

The OPP changes are mostly related to switching over from RCU-based synchronization, that turned out to be overly complicated and problematic, to reference counting using krefs. In the cpufreq land there are core cleanups, documentation updates, a new driver for Broadcom BMIPS SoCs, a new cpufreq-dt sub-driver for TI SoCs that require special handling, ARM64 SoCs support for the qoriq driver, intel_pstate updates, powernv driver update and assorted fixes. The devfreq changes are mostly fixes related to the sysfs interface and some Exynos drivers updates. Apart from that, the cpuidle menu governor will support per-CPU PM QoS constraints for the wakeup latency now, some bugs in the wakeup IRQs framework are fixed, the generic power domains framework should handle asynchronous invocations of *noirq suspend/resume callbacks from now on, the analyze_suspend.py script is updated and there is a new tool for intel_pstate diagnostics.

IB/cma: Add default RoCE TOS to CMA configfs
Add new entry to the RDMA-CM configfs that allows users to select default TOS for RDMA-CM QPs. This is useful for users that want to control the TOS for legacy applications without changing their code. Application that sets the TOS explicitly using the rdma_set_option API will continue to work as expected, meaning overriding the configfs value.

rtc: bq32000: add support to enable disable the trickle charge FET bypass
The bq32000 includes a trickle charge circuit to maintain the charge of the backup supply when a super capacitor is used. You can enable the charging circuit by setting 'trickle-resistor-ohms', additionally you can set TCFE to 1 to bypass the internal diode and boost the charge voltage of the backup supply. You might want to enable/disable the TCFE switch from userspace (e.g when device is only connected to a battery) This patch introduces a new sysfs entry to enable and disable this FET form userspace.

PM / devfreq: Simplify the sysfs name of devfreq-event device
This patch just removes '.' character from the sysfs name of devfreq-event device as following. Usually, the subsystem uses the similiar naming style such as {framework name}{Number}. - old : /sys/class/devfreq-event/event.(X) - new : /sys/class/devfreq-event/event(X) And this patch initializes the value of 'event_no' with -1 in order to remove the unneeded operation (-1) when calling the atomic_inc_return(&event_no). Lastly, this patch adds the ABI document for devfreq-event class. Signed-off-by: Chanwoo Choi <cw00.choi@samsung.com> Signed-off-by: MyungJoo Ham <myungjoo.ham@samsung.com> |

[media] rc: change wakeup_protocols to list all protocol variants
For IR wakeup, a driver has to program the hardware to wakeup at a specific IR sequence, so it makes no sense to allow multiple wakeup protocols to be selected. In the same manner the sysfs interface only allows one scancode to be provided. In addition, we need to know the specific variant of the protocol. In short, these changes are made to the wakeup_protocols sysfs entry: - list all the protocol variants rather than the protocol groups, e.g. "nec nec-x nec-32" rather than just "nec". - only allow one protocol variant to be selected rather than multiple - wakeup_filter can only be set once a protocol has been selected in wakeup_protocols. This is an API change, however the only user of this API is the img-ir, but the wakeup code was never merged to mainline, so it was never used.

leds: class: Add new optional brightness_hw_changed attribute
Some LEDs may have their brightness level changed autonomously (outside of kernel control) by hardware / firmware. This commit adds support for an optional brightness_hw_changed attribute to signal such changes to userspace (if a driver can detect them): What: /sys/class/leds/<led>/brightness_hw_changed Date: January 2017 KernelVersion: 4.11 Description: Last hardware set brightness level for this LED. Some LEDs may be changed autonomously by hardware/firmware. Only LEDs where this happens and the driver can detect this, will have this file. This file supports poll() to detect when the hardware changes the brightness. Reading this file will return the last brightness level set by the hardware, this may be different from the current brightness. Drivers which want to support this, simply add LED_BRIGHT_HW_CHANGED to their flags field and call led_classdev_notify_brightness_hw_changed() with the hardware set brightness when they detect a hardware / firmware triggered brightness change.

iio: Add STM32 timer trigger driver
Timers IPs can be used to generate triggers for other IPs like DAC or ADC. Each trigger may result of timer internals signals like counter enable, reset or edge, this configuration could be done through "master_mode" device attribute. Since triggers could be used by DAC or ADC their names are defined in include/ nux/iio/timer/stm32-timer-trigger.h and is_stm32_iio_timer_trigger function could be used to check if the trigger is valid or not. "trgo" trigger have a "sampling_frequency" attribute which allow to configure timer sampling frequency. version 8: - change kernel version from 4.10 to 4.11 in ABI documentation version 7: - remove all iio_device related code - move driver into trigger directory version 5: - simplify tables of triggers - only create an IIO device when needed version 4: - get triggers configuration from "reg" in DT - add tables of triggers - sampling frequency is enable/disable when writing in trigger sampling_frequency attribute - no more use of interruptions version 3: - change compatible to "st,stm32-timer-trigger" - fix attributes access right - use string instead of int for master_mode and slave_mode - document device attributes in sysfs-bus-iio-timer-stm32 version 2: - keep only one compatible - use st,input-triggers-names and st,output-triggers-names to know which triggers are accepted and/or create by the device Signed-off-by: Benjamin Gaignard <benjamin.gaignard@st.com> Acked-by: Jonathan Cameron <jic23@kernel.org> Signed-off-by: Lee Jones <lee.jones@linaro.org> |

First round of new device support, features and cleanups for IIO in the 4.11 cycle.
It's shaping to be another fairly busy cycle. Lots more on the way! New device support * ads7950 - new driver supporting ads7950, ads7951, ads7952, ads7953, ads7954, ads7955, ads7956, ads7957, ads7958, ads7959, ads7960, and ads7961 ADCs. * cm3605 - New driver for this light sensor and proximity sensor which is an analog part with some additional digital controls. * hx711 - New driver. Core new stuff * Gravity sensor type. This is a processed datastream in which the device will try to work out which way is down. * Split the buffer.h file into two parts. One provides the interface to 'use' a buffer, the second provides the internals of the buffer functionality as needed by implementations of buffers. - Move documentation inline so as to allow use of private: tag when generating documentation. - Add some utility functions for the few things that are directly done with the buffers. - Stop exporting functions that no-one uses outside of the core code. - Push docs down by the code in the c file where they should have always been. - Fix typo in kernel-doc for buffer. - push down some includes that were previously happening implicitly. - stop enabling the timestamp of the dummy device. Features and cleanups * ad5592r - ACPI support * ad5593r -ACPI support. * ad5933 - Fix a false comment about size of a particular register. * ad7150 - replace S_IRUGO | S_IWUSR with 0644. I'm not that keen on these patches in general, but as it was nicely presented I took this one anyway. As a general rule will only take these as part of a larger driver cleanup. - don't eat an error but rather reutnr it in the write_event_config callback. * ad7606 - replace non standard range attibute with _scale * ade7753 - use usleep_range for short sleeps * ade7754 - use usleep_range for short sleeps * ade7758 - use usleep_range for short sleeps * ade7759 - use usleep_range for short sleeps * |

Merge branch 'x86-cache-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull x86 cache allocation interface from Thomas Gleixner: "This provides support for Intel's Cache Allocation Technology, a cache partitioning mechanism. The interface is odd, but the hardware interface of that CAT stuff is odd as well. We tried hard to come up with an abstraction, but that only allows rather simple partitioning, but no way of sharing and dealing with the per package nature of this mechanism. In the end we decided to expose the allocation bitmaps directly so all combinations of the hardware can be utilized. There are two ways of associating a cache partition: - Task A task can be added to a resource group. It uses the cache partition associated to the group. - CPU All tasks which are not member of a resource group use the group to which the CPU they are running on is associated with. That allows for simple CPU based partitioning schemes. The main expected user sare: - Virtualization so a VM can only trash only the associated part of the cash w/o disturbing others - Real-Time systems to seperate RT and general workloads. - Latency sensitive enterprise workloads - In theory this also can be used to protect against cache side channel attacks" [ Intel RDT is "Resource Director Technology". The interface really is rather odd and very specific, which delayed this pull request while I was thinking about it. The pull request itself came in early during the merge window, I just delayed it until things had calmed down and I had more time. But people tell me they'll use this, and the good news is that it is _so_ specific that it's rather independent of anything else, and no user is going to depend on the interface since it's pretty rare. So if push comes to shove, we can just remove the interface and nothing will break ] * 'x86-cache-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (31 commits) x86/intel_rdt: Implement show_options() for resctrlfs x86/intel_rdt: Call intel_rdt_sched_in() with preemption disabled x86/intel_rdt: Update task closid immediately on CPU in rmdir and unmount x86/intel_rdt: Fix setting of closid when adding CPUs to a group x86/intel_rdt: Update percpu closid immeditately on CPUs affected by changee x86/intel_rdt: Reset per cpu closids on unmount x86/intel_rdt: Select KERNFS when enabling INTEL_RDT_A x86/intel_rdt: Prevent deadlock against hotplug lock x86/intel_rdt: Protect info directory from removal x86/intel_rdt: Add info files to Documentation x86/intel_rdt: Export the minimum number of set mask bits in sysfs x86/intel_rdt: Propagate error in rdt_mount() properly x86/intel_rdt: Add a missing #include MAINTAINERS: Add maintainer for Intel RDT resource allocation x86/intel_rdt: Add scheduler hook x86/intel_rdt: Add schemata file x86/intel_rdt: Add tasks files x86/intel_rdt: Add cpus file x86/intel_rdt: Add mkdir to resctrl file system x86/intel_rdt: Add "info" files to resctrl file system ... |

sound updates for 4.10-rc1
No dramatic changes are found in this development cycle, but as usual, many commits are applied in a wide range of drivers. Most of big changes are in ASoC, where a few bits of framework work and quite a lot of cleanups and improvements to existing code have been done. The rest are usual stuff, a few HD-audio and USB-audio quirks and fixes, as well as the drop of kthread usages in the whole subsystem. Below are some highlights: ASoC: - Support for stereo DAPM controls - Some initial work on the of-graph sound card - regmap conversions of the remaining AC'97 drivers - A new version of the topology ABI; this should be backward compatible - Updates / cleanups of rsnd, sunxi, sti, nau8825, samsung, arizona, Intel skylake, atom-sst - New drivers for Cirrus Logic CS42L42, Qualcomm MSM8916-WCD, and Realtek RT5665 USB-audio: - Yet another race fix at disconnection - Tolerated packet size calculation for some Android devices - Quirks for Axe-Fx II, QuickCam, TEAC 501/503 HD-audio: - Improvement of Dell pin fixup mapping - Quirks for HP Z1 Gen3, Alienware 15 R2 2016 and ALC622 headset mic Misc: - Replace all kthread usages with simple works -----BEGIN PGP SIGNATURE----- Version: GnuPG v2 iQIcBAABAgAGBQJYUGNQAAoJEGwxgFQ9KSmkc3kP/jS5EDPWb6dwqdlZomT0lumR flpvLLo6TWTi9CS8MkC1hPHbR+3LGPMUL8Wwf2cVb06dvKpUHa5P3Wq6lMm6T9wO 1ExhnHeDEDfGXop3/EuADmpRsfsV+z/PpWYmGB0vkoyPTg7e3xQRA6Im6p6IMi45 pnvEaSe18oEidqzAxaBgBFTdoNyaD9zrPL5J9Jh0/JCZ/kSmY6hhI+hlTjjOKCR6 fs4ge2WreonAKbhfOE61eE2KDnQA4II/2JUoPA42wZOat9ukb8DiErgHoFgsWTtE h+/ZN5Qj3dweP3+NIKsWrmfC6qzTt9OnUNPB2O0A+UYmAMQBjBz9KVxW1FHyTqBp ewATtvCNIQs+uPMaO/Q/Qo3ZkKLf/W7o/Dt2u/orSrnQ2plKgIOiHJodhXlTrOWm szF+qJq0xRB7+/dZa+gDjGPAjirr6n3Fv7wrJmqfyF0hLaIEy4wa2Rd/IAZ9Ar46 5S4prL2Ba1CKf1YV27DR1bjUTAonlApfczNp+urCGQJCfZ0kQOAhZJQ/mbMOgSDS KEC0vY6NLr88b19OETS4oQZ0ixxIAm8hwAle6z39GGhGZ8JWH5+JRzy8emVh2bss lpFLFHLwK+a+JHxmnOniJW9AlC8I7hVqfS63qaTXfvDnMMcRd5fMgniZt8bTWc2/ F5hsE83JUlcA8Owfyoca =WZeb -----END PGP SIGNATURE----- Merge tag 'sound-4.10-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound Pull sound updates from Takashi Iwai: "No dramatic changes are found in this development cycle, but as usual, many commits are applied in a wide range of drivers.

Driver core patches for 4.10-rc1
Here's the new driver core patches for 4.10-rc1. Big thing here is the nice addition of "functional dependencies" to the driver core. The idea has been talked about for a very long time, great job to Rafael for stepping up and implementing it. It's been tested for longer than the 4.9-rc1 date, we held off on merging it earlier in order to feel more comfortable about it. Other than that, it's just a handful of small other patches, some good cleanups to the mess that is the firmware class code, and we have a test driver for the deferred probe logic. All of these have been in linux-next for a while with no reported issues.

Staging/IIO patches for 4.10-rc1
Here's the "big" staging/iio pull request for 4.10-rc1. Not as big as 4.9 was, but still just over a thousand changes. We almost broke even of lines added vs. removed, as the slicoss driver was removed (got a "clean" driver for the same hardware through the netdev tree), and some iio drivers were also dropped, but I think we ended up adding a few thousand lines to the source tree in the end. Other than that it's a lot of minor fixes all over the place, nothing major stands out at all. All of these have been in linux-next for a while.

Merge branch 'for-4.10/block' of git://git.kernel.dk/linux-block
Pull block layer updates from Jens Axboe: "This is the main block pull request this series. Contrary to previous release, I've kept the core and driver changes in the same branch. We always ended up having dependencies between the two for obvious reasons, so makes more sense to keep them together. That said, I'll probably try and keep more topical branches going forward, especially for cycles that end up being as busy as this one. The major parts of this pull request is: - Improved support for O_DIRECT on block devices, with a small private implementation instead of using the pig that is fs/direct-io.c. From Christoph. - Request completion tracking in a scalable fashion. This is utilized by two components in this pull, the new hybrid polling and the writeback queue throttling code. - Improved support for polling with O_DIRECT, adding a hybrid mode that combines pure polling with an initial sleep. From me. - Support for automatic throttling of writeback queues on the block side. This uses feedback from the device completion latencies to scale the queue on the block side up or down. From me. - Support from SMR drives in the block layer and for SD. From Hannes and Shaun. - Multi-connection support for nbd. From Josef. - Cleanup of request and bio flags, so we have a clear split between which are bio (or rq) private, and which ones are shared. From Christoph. - A set of patches from Bart, that improve how we handle queue stopping and starting in blk-mq. - Support for WRITE_ZEROES from Chaitanya. - Lightnvm updates from Javier/Matias. - Supoort for FC for the nvme-over-fabrics code.

VFIO updates for v4.10-rc1
- VFIO updates for v4.10 primarily include a new Mediated Device interface, which essentially allows software defined devices to be exposed to users through VFIO. The host vendor driver providing this virtual device polices, or mediates user access to the device. These devices often incorporate portions of real devices, for instance the primary initial users of this interface expose vGPUs which allow the user to map mediated devices, or mdevs, to a portion of a physical GPU. QEMU composes these mdevs into PCI representations using the existing VFIO user API. This enables both Intel KVM-GT support, which is also expected to arrive into Linux mainline during the v4.10 merge window, as well as NVIDIA vGPU, and also Channel I/O devices (aka CCW devices) for s390 virtualization support. (Kirti Wankhede, Neo Jia) - Drop unnecessary uses of pcibios_err_to_errno() (Cao Jin) - Fixes to VFIO capability chain handling (Eric Auger) - Error handling fixes for fallout from mdev (Christophe JAILLET) - Notifiers to expose struct kvm to mdev vendor drivers (Jike Song) - type1 IOMMU model search fixes (Kirti Wankhede, Neo Jia) -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.14 (GNU/Linux) iQIcBAABAgAGBQJYSyCtAAoJECObm247sIsi+rIP/3Q/GE3zaDdz1iKQK/c/qhs6 0Pl45opAqw4wCJDCZIhRmoHmsCaT4KkeJKU1fiYc0mKJhW11HfA4DTFwzBqrHBj7 7wPjHTaWwlFRHCYVCWYEp5g9UASyD8ubWGyZKzqIXELFoAvwuBL3SULNj4neJKKR rPcHTVxJ7laYIjHFzuNUi/MWEdjxPT9oJn8Bm9mhISwPglIMU9nkIR20ChaSeFJb MiFqFW7BcvkVyqupjpksM9DodpNZu+3uSMVtgASNVNbilf0FXJr0d8RCbeSxTIfm rEsZ5+0PrklhCtmRRl5EB+tNawgaism8wAF74KIO//76vE02Usrxb0b5mTIZ8TiN 6/Z+WID5D+ZRt8hp9hJIJmGE/sM/odH4r174dPaiEkMvOB9ksDIPkzgbtDbVY40c DACb7/n3ZZA0an2Eq2HEx/BqTOvt9sgu367KVvhuoIArQcb5SM94GT03Dv+pKnax Cxmro2oaWmAV3IS0vNzbCIddsFqlPjkFIYxjtzBy+bVLg2RN3STyaSL6cwJsydSU KLcCPiYtovczKFj7RJlgVlqh5/8uZ7SEffTkIggehdnVPAfDlK9p9BYqLCgAoWpN vwWidM3qOIjooRXQgxUwJgJsl4MLRMoA/gFP4iHbqOgIAGtUDRHuQ4muvkf+LLxg wpgfXsBQNRuVcZHBUEVe =gc6j -----END PGP SIGNATURE----- Merge tag 'vfio-v4.10-rc1' of git://github.com/awilliam/linux-vfio Pull VFIO updates from Alex Williamson: - VFIO updates for v4.10 primarily include a new Mediated Device interface, which essentially allows software defined devices to be exposed to users through VFIO.

remoteproc updates for v4.10
Introduces remoteproc "subdevice" support, which allows remoteproc driver to associate devices to the "running" state of the remoteproc, allowing devices to be probed and removed as the remote processor is booted, shut down or recovering from a crash. Handling of virtio device resources was improved, vring memory is now allocated as part of other memory allocation. This ensures that all vrings for all virtio devices are allocated before we boot the remote processor. The debugfs mechanism for starting and stopping remoteproc instances was replaced with a sysfs interface, also providing a mechanism for specifying firmware to use by the instance. This allows user space to load and boot use case specific firmware on remote processors. New drivers for the ST Slimcore and Qualcomm Hexagon DSP as well as removal of the unused StE modem loader. Finally support for crash recovery in the Qualcomm Wirelss subsystem (used for WiFi/BT/FM on a number of platforms) and a number of bug fixes and cleanups. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1 iQIcBAABAgAGBQJYTzfjAAoJEAsfOT8Nma3Fcs0P/irQd7U3gW14XFnl4ObdCOSO WlfG6jYP3fkWYA/ynxmu1FbRsyjP1aCrTRmW7oUGtTjCey8oUj69jo2+nLm0yx1k EtaTM+72hc7wULaGCBVvmA+LdQRRmTof9uJEjKvDyC8FAY0Thyvu77qlXQ5BrJkN o9xNVPDne/1RZx8vVI/zGEeL5+pNK1LXVy0vtFdG89acimu8yIJWJGS0IabnEWLs 8US6kpxROwkLefuTD4Rs4ByL6S5+1pHwVM6L/5GxsMawMzOhvzYgRa0SNNh7cNO/ e5ND7dUTcCt7lMOnpbSfqm2BbVRky6ATsoYrOdnVEH9sYJkQ9pMONadHIlVZFwce YVDp0UwEasf2IMtAFlvxDI31C5Wm8lpYOL7eixkkVrI1DJaBj8+Ih38F2IruWl9R QeDSFH/8a9l6fyN6RIUuPR8b1eeurl+CDoYWKEN6vzXDSi8GqsElB70xIAN/Umdq wdJvJByfitYLKEHenG5+mnQrDTQJ0C2f45hynkTCfJY1Qdl6nsMQi5sZFrE8HpOs dXFnpg/YK98wWmjyADEYDziH2y5oMHM6r5uljjcKOJDnzwLsDh8WQqhH4dNPNZBA 2+b4ouhbJLwYMM3zpem8JvV0rIsXvn3Kc8VNKcWOtHymkn8hLQ6Zexsr+RkbttQL Em5DvXL5lPm7wVYHvgP8 =/1kU -----END PGP SIGNATURE----- Merge tag 'rproc-v4.10' of git://github.com/andersson/remoteproc Pull remoteproc updates from Bjorn Andersson: - introduce remoteproc "subdevice" support, which allows remoteproc driver to associate devices to the "running" state of the remoteproc, allowing devices to be probed and removed as the remote processor is booted, shut down or recovering from a crash. - handling of virtio device resources was improved, vring memory is now allocated as part of other memory allocation.

block: add support for REQ_OP_WRITE_ZEROES
This adds a new block layer operation to zero out a range of LBAs. This allows to implement zeroing for devices that don't use either discard with a predictable zero pattern or WRITE SAME of zeroes. The prominent example of that is NVMe with the Write Zeroes command, but in the future, this should also help with improving the way zeroing discards work. For this operation, suitable entry is exported in sysfs which indicate the number of maximum bytes allowed in one write zeroes operation by the device.

PCI: Create revision file in sysfs
Currently the revision isn't available via sysfs/libudev thus if one wants to know the value one needs to read through the config file, which can be quite time-consuming because it wakes/powers up the device. There are at least two userspace components which could make use the new file: libpciaccess and libdrm. The former wakes up _every_ PCI device, which can be observed via glxinfo when using Mesa 10.0+ drivers. The latter, in association with Mesa 13.0, can lead to 2-3 second delays while starting firefox, thunderbird or chromium.

PM / sleep: System sleep state selection interface rework
There are systems in which the platform doesn't support any special
sleep states, so suspend-to-idle (PM_SUSPEND_FREEZE) is the only
available system sleep state. However, some user space frameworks
only use the "mem" and (sometimes) "standby" sleep state labels, so
the users of those systems need to modify user space in order to be
able to use system suspend at all and that may be a pain in practice.

phy: rcar-gen3-usb2: add sysfs for usb role swap
This patch adds sysfs "role" for usb role swap. This parameter can be read and write. If you use this file as the following, you can swap the usb role. For example: 1) Connect a usb cable using 2 Salvator-x boards 2) On A-Device (ID pin is low), you input the following command: # echo peripheral > /sys/devices/platform/soc/ee080200.usb-phy/role 3) On B-Device (ID pin is high), you input the following command: # echo host > /sys/devices/platform/soc/ee080200.usb-phy/role Then, the A-device acts as a peripheral and the B-device acts as a host. Please note that A-Device must input the following command if you want the board to act as a host again. (even if you disconnect the usb cable, since id state may be the same, the A-Device keeps to act as peripheral.) # echo host > /sys/devices/platform/soc/ee080200.usb-phy/role Signed-off-by: Yoshihiro Shimoda <yoshihiro.shimoda.uh@renesas.com> Reviewed-by: Peter Chen <peter.chen@nxp.com> Signed-off-by: Kishon Vijay Abraham I <kishon@ti.com> |

Third set of IIO new device support, features and cleanup for the 4.10 cycle.
Includes Peter Rosin's interesting drivers for a comparator. First complex use we have had with an analog front end made from discrete components. Brian Masney's work on moving the tsl2583 driver out of staging also feature extensively! New Drivers * DAC based on a digital potentiometer - New driver for the use of a dpot as a DAC. Includes bindings and Axentia entry in vendor prefixes. * Envelope detector baed on DAC and a comparator including device tree bindings. Staging Graduation * tsl2583. Core new features - Core provision for _available attributes. This one had been stalled for a long time until Peter picked it up and ran with it! - In kernel interface helpers to retrieve available info from channels. Driver new features * mcp4531 - Add range of available raw values (used for the dpot dac driver). Driver cleanups and fixes for issues introduced * ad7766 - Testing the wrong variable following devm_regulator_bulk_get introduced with the driver earlier in this cycle. * ad9832 - Fix a wrong ordering in the probe introduced in the previous set of patches. A use before allocation bug. * cros_ec_sensors - Testing for an error in a u8 will never work. * mpu3050 - Remove duplicate initializer for the module owner. - Add missing i2c dependency. - Inform the i2c mux core how it is used - step one in implifying device tree bindings. * st-sensors - Get rid of large number of uninformative defines in favour of putting the constants where they are relevant. It is clear what they are from where they are used. * tsl2583 - Fix unused function warning when CONFIG_PM disabled and remove the ifdefs in favour of __maybe_unused. - Refactor taos_chip_on to only read relevant registers. - Make sure calibscale and integration time are being set. - Verify chip is in ready to be used before calibration. - Remove some repeated checks for chip status (it's protected by a mutex so can't change until it's released) - Change current state storage from a tristate enum to a boolean seeing as only two values are actually used now. - Drop a redundant write to the control regiser in taos_probe (it's a noop) - Drop the FSF mailing address. - Clean up logging to not use hard coded function names (use __func__ instead). - Cleanup up variable and function name prefixes. - Alignment of #define fixes. - Fix comparison between signed and unsigned integer warnings. - Add some newlines in favour of readability. - Combine the two sysfs ABI docs that somehow ended up in different places. - Fix multiline comment syntax. - Move a code block to inside an else statement as it makes more sense there. - Change tsl2583_als_calibrate to return 0 rather than a value nothing reads. - Drop some pointless brackets - Don't assume 32bit unsigned int. - Change to a per device instance lux table. - Add missing tsl2583 to the list of supported devices in the intro comments. - Improve commment on clearing of interrupts. - Drop some uninformative comments. - Drop a memset call that doesn't do anything useful any more. - Don't initialize some return variables that are always set. - Add Brian Masney as a module author after all these changes. -----BEGIN PGP SIGNATURE----- iQIuBAABCAAYBQJYKMYhERxqaWMyM0BrZXJuZWwub3JnAAoJEFSFNJnE9BaIiNMP /00ZTTfPR/I5VtriTchGTgXN6lDTnypFk9Z4niynK3EIdF6Mw5XphQjtUzg7sJl4 U7yH89lzt0PxAJHylW5x0YOwrr6fyau+rNA2Kj26psaQpf5Yva0UDRexsomTZaad P005cf0yc4fuG/7KvjeONeLeaRXf9Qfs20r8htECLFhIGSE0qsGtfzUMn6tdbyn/ r/hxHR7oE2YThuFytX2sNJEJVmCDz+tTOz7kJv5L0e6Cg6cvMFizYUsoFYcZYGOQ DNicdRfW5FOidBMCqXzYLDBn+oY+a35g90hFV3CvYsfEm+X6BzTgr3FI3PHmtXHT RRAmRdgxg2z/rqp475f5EamRtZxEg0uktbqcs9bH8Bx7IDe8KtoNKLdPdxIT3T1D ZYb0RkpPmfnBq3bDGh7DJVWl+Ht9Fj0jaKRNyWgiyopA9c6zN4MKRA+HNSxKRvD7 Qizw0QIPbtEGkw6WbQrrOSSwzNY/dq51vrT0eBmMaGpjmdDpRKrK53/k7uwk3/Wv hjGWD5kdLRCAHL+EQKFssN/RgLS5PRhXsJQFeIYbH8VJFlEZ28j09gXJnjcpDucK CXv37q8CX6wJ2NB+i+skOvKpxArgv+Mr4oE9LNYZie65EUyN28/Ii1n9vYmTPTlG KXGKPynaR0sfrl+ir6+FCtuFXJnYC5WUqJH/yMRjA2z8 =mPkb -----END PGP SIGNATURE----- Merge tag 'iio-for-4.10c' of git://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio into staging-next Jonathan writes: Third set of IIO new device support, features and cleanup for the 4.10 cycle.

remoteproc: Add a sysfs interface for firmware and state
This patch adds a sysfs interface to rproc allowing the firmware name and processor state to be changed dynamically. State was previously available in debugfs, and is replicated here. The firmware file allows retrieval of the running firmware name, and a new one to be specified at run time, so long as the remote processor has been stopped.

First round of IIO new device support, features and cleanups for the 4.10 cycle.
Fair number of outreachy related patches in here. Some of these may well have already been picked up by Greg but git will sort that out for us. Also some good staging cleanup work from other sources. Thanks Brian and Lars in particular for this. New device support * ACCES 104-quad-8 - New driver for this 8 channel encoder input board. Lots of new ABI with this one. * AD7766 - New driver supporting AD7766, AD7766-1, AD7766-2, AD7767, AD7767-1 and AD7767-2 24 bit ADCs. * dmard 10 - New driver for this 3 axis accelerometer. * Honeywell ABP pressure sensors. - New driver covering 56 parts in this series (too many to list here!) * HTS221 - New driver to support this relative humidiy and temperature device. * LMP91000 - New driver for this potentiostat (form of chemical sensor). Nice example of use of the buffered consumer interfaces and the use of a consumer provided trigger. * MiraMEMS DA311 - New driver for this 3 axis accelerometer. * MiraMEMS DA280 - New driver for this 3 axis accelerometer. Follow up caught up with vendor prefixes for these. Staging graduations * isl29018 light sensor - Fixes and cleanups listed below (thanks for your hard work on this Brian!) * sca3000 - Fixes and cleanups listed below. This was one of the small set of drivers that went into staging when IIO was first added. Turns out it had a few bugs and needed to be brought into the modern era! Not clear if I am the only person who actually has one of these still wired to a board. New features (Core) - Add an iio_trigger_validate_own_device helper which relies on the device and trigger having the same parent. Convenient to have this for some of the more complex trigger / device interactions. Was hand rolled in a few drivers already so good to bring it into the core. - Add an iio_read_channel_offset in kernel access helper (similar to the existing one for scale). - IIO_ATTR_{RO, WO, RW} and IIO_DEVICE_ATTR_{RO, WO, RW} macros. These lead some rather contrived function naming, but there is no denying they do reduced boilerplate. I'm going to resist their introduction in drivers 'unless' they form part of a larger set of cleanups. - Counter channel type and index type. New features (Drivers) * hdc100x - Triggered buffer support. * mcp4725 - Device tree bindings and support. - Voltage reference selection. * ti-adc0832 - Triggered buffer support. * ti-adc161s626 - Add regulator support allowing _scale and _offset values to be established and exported. New features (Tools) * iio_generic_buffer - -A option to force enable all channels rather than faulting if some are already enabled (like -a does). Followup patches tidied this support up. Cleanups (Core) - Use kmalloc_array in iio_scan_mask_set. - Take event_attrs field of iio_info structure constant - Staging todo list updates. Most of it was long done. - MAINTAINERS had a wrong directory listing. Cleanups (Drivers) * Missing i2c trivial devices entries. * ad5592r - Fix an endian type related sparse warnings. * ad7150 - Constify the event attribute_group structures. * ad7152 - Add some blank lines to improve readability. - Sampling frequency control via chan-info element rather than hand rolled attributes. - add a new lock to avoid use of mlock for non state change related locking. * ad7280 - Constify atrribute_group structure (second patch covers the event ones) * ad7606 (Lars is driving most of the cleanup on this with some additions from Eva) - Fix improper setting of oversampling pins. This has been broken a very long time in this staging driver, so not going to push this back to stable. - Implement oversampling configuration via the chan_info mask element. - Remove an unused int_vref_mv field. - Remove a reundant name field from ad7606_chip_info. - Remove default device configuration from platform_data in favour of whatever the power on defaults are. - Remove out of band error reporting in the kernel log as not providing much information. - Fix oversampling ratio by having 1 be the value for no oversampling. - Avoid allocating buffer for each data capture. - Factor out common code between periodic and one-shot capture. - Move set_drvdat into common code. - Let the common probe function return int rather than jumping through an ERR_PTR. - Pass struct device * into common remove to simplify code. - Always run trigger handler only once per event (no one can remember why it was being possibly done twice). - Move over to the GPIO descriptor API to shorten and clarify code. - Move the buffer code into the main file as it's not optional and is now rather short in this driver. - Fix the naming of the supply regulator. - Rework regulator handling to handle errors including deferred probing. - Tidy up a ptr_err or 0 return. * ad7746 - Sampling frequency control via info_mask element rather than hand rolled * ad7758 - Sampling frequency control via info_mask element rather than hand rolled attributes. * ad7816 - Constify the event attribute_group structure. * adt7316 - Constify the event attribute group structures. * ak8974 - Cleanup some sparse warnings about endian types. * ak8975 - Cleanup some sparse warnings about endian types. * bmi160 - Spare endian warning cleanups. * isl29018 (towards staging graduation) - Remove unusedvariables and defines. - Improve consistency of error handling. - Signed / unsigned comparison fixes. - Use the IIO_DEVICE_ATTR_{RO, RW} macros - Fix a race in in_illuminance_scale_available_show. - Cleanup exit points of _read_raw - Sanity check if in suspended state during a write_raw call as was already done for read_raw. - Document device tree bidnings. - Document infrared supression controls. - Add some newlines to improve readability and drop one that shouldn't be there. - Fix a poorly named functions name. - Fix multiline coment syntax. - Tidy up a pair or return statements by unifying them. - Rename description in Kconfig for consistency with similar drivers. * lidar - cleanup power management by dropping unnecessary call. * ltr501 - Use the claim_direct_mode helpers. Fix a race condition along the way. * max1027 - Fix a dubious x | !y sparse warning. - Use the new iio_trigger_validate_own_device helper. * max440000 - Clean up some sparse warnings about endian types. * mcp4725 - Use the regulator framework to establish the reference voltage rather than getting it from platform data. - Tidy up a comment typo. - Fix a wrong PTR_ERR query (wrong regulator). * mma7660 - Take a mma7660_nscale static. * mma8452 - Use the new iio_trigger_validate_own_device helper. - Use claim_direct_mode helpers - fix a race condition along the way. * mpl3115 - Use claim_direct_mode helpers - fix a race condition along the way. * ms65611 - Tidy up regulator error handling and clean out a static warning in the mix. * sca3000 - Avoid a potential unitialized variable if a hardware read returns a value that isn't actually supported (mostly warning supression). - Fix a use before setting of the indio_dev->buffer pointer. Broken for a very long time so not going to rush this into stable. - Merge buffer file with core file. We used to always split these. Sometimes it's just not worth the hassle. In this case the device's main feature is it's hardware fifos so unlikely anyone would want to run it without. - Drop the sca3000_register_ring_funcs function as it's a pointless wrapper once we have only one file. - Fix cleaning of flag + setting of size of scan. Without this you can't start the buffer twice and expect sensible (or any) results. Again, broken for a long time so not heading for stable. - Drop the custom watershed setting ABI - for now we'll just support one value. - Move to a hybrid hard / soft buffer design (how we've been doing it for similar devices for a while now!) - Cleanup some unusued variables. - Use a fake channel to support core handling of freefall event registration. - Cleanup the register defines. - Fix an off by one error in axis due to IIO_NO_MOD taking up the 0 value. Been broken since first admission of IIO to the staging tree. - Add readback of the 3db low pass filter frequency and later writing allowing droppign of custom measurement mode attributes as they can be represented by the filter choices that is their main characteristic. - Drop non standard revision attr and replace with dev_info on probe. - Avoid a race in probe. - Various formatting fixes. - Kernel-docify docs that were very nearly in the write format. * tsl2583 - Constify attribute_group structure. * zpa2326 - Drop a redundant DEBUG ifdef. Cleanups (Tools) * iio_generic_buffer - Fix the ? arguement. Previously it sort of worked as you got the help message as a result of it not recognising the arguement. -----BEGIN PGP SIGNATURE----- iQIuBAABCAAYBQJYDSX+ERxqaWMyM0BrZXJuZWwub3JnAAoJEFSFNJnE9BaIQSEP /2HRMqDXeIh2N0oVLBFK5pEaAZ52tjsEmf1XgfCJ3D1PczS0vzqkFKuG/078BU3v e9MTj39sF1EOyGJv4mdfnHygLPvjaTU/A6HoIaP1t9cUgSQ1jzPN0tO8/Hj/ESlU U3mNgUNUIa9cnVIfWk2cPJqgKJ/w52vRk00yRnOKZjHZkxbYQq9rPJ7ks12jQSGT IBEipiYMnRovc2w4NWbAry5pAXBmttVFKyi5FZ7uIM5EH34+SAY6laXSoZQl8E74 LKgIwdPUn9yeujyX6ohBFRFloOf/4VYedV6NIUz8k5BzuTeAJcp4DSMLXSWIwZVd sdza6el3Tt0MkjIgioTg7N07FvatbQVIsnWnLjLb/zpMjGQPigfTnIi7kYcH3wHx NwpTy1MZg5U571LOYXsEhNvIFiQICoV6+8d/PzrO1J+rphuQYreOm0WzjvIqW4q/ dU2uCAMOHd82gjm9QrKjvrc+4M3oGc3ENE/i5P2YNQhdkdNKp9PMWgL6RO9QXgeQ 9TrjbDr9OSFLatZg5IswWFa5CHL9AZ6OuvaRyx/8n5cBdY3n8+wMIowRQJlMUdGY Aa5ByntMsvhwCu+M1+fDihZyx4suTNvW7+Emqd/8lCb+BRjHoamBb6uGBGx6Txvy 6TPluNWE+cK5Tjkrn+jDbTzhwdaaSRtO4ECRwxXYAqfn =ZRUt -----END PGP SIGNATURE----- Merge tag 'iio-for-4.10a' of git://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio into staging-next Jonathan writes: First round of IIO new device support, features and cleanups for the 4.10 cycle.

cxl: Prevent adapter reset if an active context exists
This patch prevents resetting the cxl adapter via sysfs in presence of
one or more active cxl_context on it. This protects against an
unrecoverable error caused by PSL owning a dirty cache line even after
reset and host tries to touch the same cache line. In case a force reset
of the card is required irrespective of any active contexts, the int
value -1 can be stored in the 'reset' sysfs attribute of the card.
The patch introduces a new atomic_t member named contexts_num inside
struct cxl that holds the number of active context attached to the card
, which is checked against '0' before proceeding with the reset. To
prevent against a race condition where a context is activated just after
reset check is performed, the contexts_num is atomically set to '-1'
after reset-check to indicate that no more contexts can be activated on
the card anymore.
Before activating a context we atomically test if contexts_num is
non-negative and if so, increment its value by one. In case the value of
contexts_num is negative then it indicates that the card is about to be
reset and context activation is error-ed out at that point.

block: Add 'zoned' queue limit
Add the zoned queue limit to indicate the zoning model of a block device. Defined values are 0 (BLK_ZONED_NONE) for regular block devices, 1 (BLK_ZONED_HA) for host-aware zone block devices and 2 (BLK_ZONED_HM) for host-managed zone block devices. The standards defined drive managed model is not defined here since these block devices do not provide any command for accessing zone information. Drive managed model devices will be reported as BLK_ZONED_NONE. The helper functions blk_queue_zoned_model and bdev_zoned_model return the zoned limit and the functions blk_queue_is_zoned and bdev_is_zoned return a boolean for callers to test if a block device is zoned. The zoned attribute is also exported as a string to applications via sysfs. BLK_ZONED_NONE shows as "none", BLK_ZONED_HA as "host-aware" and BLK_ZONED_HM as "host-managed".

iio: 104-quad-8: Add IIO support for the ACCES 104-QUAD-8
The ACCES 104-QUAD-8 is a general purpose quadrature encoder counter/interface board. The 104-QUAD-8 is capable of monitoring the outputs of eight encoders via four on-board LSI/CSI LS7266R1 24-bit dual-axis quadrature counter chips. Core functions handled by the LS7266R1, such as direction and total count, are available. Performing a write to a counter's IIO_CHAN_INFO_RAW sets the counter and also clears the counter's respective error flag. Although the counters have a 25-bit range, only the lower 24 bits may be set, either directly or via a counter's preset attribute. Interrupts are not supported by this driver. This driver adds IIO support for the ACCES 104-QUAD-8 and ACCES 104-QUAD-4. The base port addresses for the devices may be configured via the base array module parameter.

usb: core: Introduce a USB port LED trigger
This commit adds a new trigger responsible for turning on LED when USB device gets connected to the selected USB port. This can can useful for various home routers that have USB port(s) and a proper LED telling user a device is connected. The trigger gets its documentation file but basically it just requires enabling it and selecting USB ports (e.g. echo 1 > ports/usb1-1). There was a long discussion on design of this driver. Its current state is a result of picking them most adjustable solution as others couldn't handle all cases. 1) It wasn't possible for the driver to register separated trigger for each USB port. Some physical USB ports are handled by more than one controller and so by more than one USB port. E.g. USB 2.0 physical port may be handled by OHCI's port and EHCI's port. It's also not possible to assign more than 1 trigger to a single LED and implementing such feature would be tricky due to syncing triggers and sysfs conflicts with old triggers. 2) Another idea was to register trigger per USB hub. This wouldn't allow handling devices with multiple USB LEDs and controllers (hubs) controlling more than 1 physical port. It's common for hubs to have few ports and each may have its own LED. This final trigger is highly flexible. It allows selecting any USB ports for any LED. It was also modified (comparing to the initial version) to allow choosing ports rather than having user /guess/ proper names. It was successfully tested on SmartRG SR400ac which has 3 USB LEDs, 2 physical ports and 3 controllers. It was noted USB subsystem already has usb-gadget and usb-host triggers but they are pretty trivial ones. They indicate activity only and can't have ports specified. In future it may be good idea to consider adding activity support to usbport as well. This should allow switching to this more generic driver and maybe marking old ones as obsolete. This can be implemented with another sysfs file for setting mode. The default mode wouldn't change so there won't be ABI breakage and so such feature can be safely implemented later. There was also an idea of supporting other devices (PCI, SDIO, etc.) but as this driver already contains some USB specific code (and will get more) these should be probably separated drivers (triggers).

genirq: Expose interrupt information through sysfs
Information about interrupts is exposed via /proc/interrupts, but the format of that file has changed over kernel versions and differs across architectures. It also has varying column numbers depending on hardware. That all makes it hard for tools to parse. To solve this, expose the information through sysfs so each irq attribute is in a separate file in a consistent, machine parsable way. This feature is only available when both CONFIG_SPARSE_IRQ and CONFIG_SYSFS are enabled. Examples: /sys/kernel/irq/18/actions: i801_smbus,ehci_hcd:usb1,uhci_hcd:usb7 /sys/kernel/irq/18/chip_name: IR-IO-APIC /sys/kernel/irq/18/hwirq: 18 /sys/kernel/irq/18/name: fasteoi /sys/kernel/irq/18/per_cpu_count: 0,0 /sys/kernel/irq/18/type: level /sys/kernel/irq/25/actions: ahci0 /sys/kernel/irq/25/chip_name: IR-PCI-MSI /sys/kernel/irq/25/hwirq: 512000 /sys/kernel/irq/25/name: edge /sys/kernel/irq/25/per_cpu_count: 29036,0 /sys/kernel/irq/25/type: edge [ tglx: Moved kobject_del() under sparse_irq_lock, massaged code comments and changelog ] Signed-off-by: Craig Gallek <kraig@google.com> Cc: David Decotigny <decot@google.com> Link: http://lkml.kernel.org/r/1473783291-122873-1-git-send-email-kraigatgoog@gmail.com Signed-off-by: Thomas Gleixner <tglx@linutronix.de> |

Aside from that there's a bunch of updates and cleanups for existing drivers, as well as the addition of new drivers for the Broadcom iProc, STMPE and ChromeOS EC controllers. -----BEGIN PGP SIGNATURE----- Version: GnuPG v2 iQI2BAABCAAgBQJXpLFKGRx0aGllcnJ5LnJlZGluZ0BnbWFpbC5jb20ACgkQ3SOs 138+s6E2Nw/9FggtgYlVQRS5lzwTKxQI/5HMlOfdyH84S76fUS8uAxvEsZvyHXZ7 NiwCJMkmMqPHMlrfuXacs4nueKz3jvy8csaffH5T2yHf0ZPGmkxBsdX97rvQp3z/ WTUXX8vo8fiEPQSXQOUzIYk10s7CBO2094uL8FBqfYeSySY3Ti35SpmZSQKVd1LS A1rR/qRgNbIlhI7+L5CotdrNMkHXqHZIHDyXO1dWBDVL+3MU3IPpB//J/WjU/OMs 5MHEtTr7943s8LQYhM1p5PFDn8ehe31L1quSswmMTLuepPrTUjD31476VYW8p8gg lzOv5JF5b8Rkw0B+4vDC0z/OPZA47tg8DfiS9Sa1SrCGxslOH7pvI7m9dV89FOc2 /hA1n048jBhIrHPylXZ+hUPKNM0WTwFrHVxROgtEb6/wtYskgOFGQrYKpD4FtH+j zqXxvCRMX4ZLLXy2QO4GAW3dv51pLjiM2yxVWtM1lWFWiKKvRoqHiFcnmCJJwQ4T NXUPnyt+G/GCtpVHlMtHW9YszJ650ECt+H8I1EhuGLkpOXncCPdmw34oR1wSmMi3 +1yjCvZV8bNJLt2GQDpoFEUc1dqY6g/SLqm9sz+W69QYA0oDt9JpFK+RFw118282 EX24GT9+PYe0kMt1WWopjHeFZ+6HhsG/ODwOUOaG/8kp6qZLB4EKP9k= =TdEI -----END PGP SIGNATURE----- Merge tag 'pwm/for-4.8-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/thierry.reding/linux-pwm Pull pwm updates from Thierry Reding: "This set of changes improve some aspects of the atomic API as well as make use of this new API in the regulator framework to allow properly dealing with critical regulators controlled by a PWM.

arm64: cpuinfo: Expose MIDR_EL1 and REVIDR_EL1 to sysfs
It can be useful for JIT software to be aware of MIDR_EL1 and REVIDR_EL1 to ascertain the presence of any core errata that could affect code generation. This patch exposes these registers through sysfs: /sys/devices/system/cpu/cpu$ID/regs/identification/midr_el1 /sys/devices/system/cpu/cpu$ID/regs/identification/revidr_el1 where $ID is the cpu number. For big.LITTLE systems, one can have a mixture of cores (e.g. Cortex A53 and Cortex A57), thus all CPUs need to be enumerated. If the kernel does not have valid information to populate these entries with, an empty string is returned to userspace.

ACPI: add support for loading SSDTs via configfs
New tables can be loaded by creating directories under /config/table/ and writing the AML code into the aml table attribute. Various table attributes will be readable once the table is successfully loaded. Unloading tables is not supported at the moment, but it can be easily implemented once ACPI loading functions provide a table handle to be used for unloading.

First round of IIO new device support, features and cleanups for the 4.8 cycle.
New device support * ads1015 - add ads1115 support * bma220 accelerometer - new driver - triggered buffer support. * bmc150 - add bmm150 support. * bmp280 - bme280 support with addition of humidity channel. * max5487 potentiometer - new driver * MMA7660FC accelerometer. - New driver * st-pressure - support for the lps22hb * loop trigger. - This one is *nasty* but we have real applications (parrot drones) where it is useful. The trigger basically spins as hard as it can firing off a new trigger each time all triggered devices come back to say they are done. It doesn't hang a machine even when doing it on a dummy driver. A lot nicer than having this implemented within lots of device drivers anyway. Core stuff * Add support to create IIO devices via configfs (similar to we did for triggers a while back) + docs. * New channel types - IIO_ELECTRICAL_CONDUCTIVITY * Couple of MAINTAINERS patches to list the device tree bindings. * Make trigger ops structure non optional (comment fix). It hasn't been for an awful long time, but that's not what the description said. New features * ak8975 - support adapters that are limited to byte data only by allowing the emulated block read i2c function that was recently introduced. * atlas-ph - support atlas-ec (electrical conductivity sensor) * bmi160 - add available frequency and scale attributes to make the driver more user friendly (and avoid having to read the datasheet to know what will work). * dummy - move creation to configfs interface. It's not real hardware so we are not that worried about the ABI breakage ;) * mma8452 - oversampling ration support * nau7802 - expose available gains to make life easier for userspace. * st-sensors - allow use of emulation for SMBus block reads as all the st parts support it. * ti-ads1015 - list datasheet names to allow their use by inkernel consumers. * Various module alias additions to help auto probing. Drop one redundant one as well. Cleanups * ad7266, ad7476, ad7887, ad7923, ad799x - use direct mode claim function rather than open coding it during sensor read (prevents switching on buffers mid read). * ad7793, ad7791 - use direct mode claim to prevent frequency changes when buffers running. * afe440x - These are ABI breaking but the driver requires custom userspace code to do anything useful anyway and that is still being written and under control of TI. Ultimately we may have other libraries to do pulse oximetry with these devices but we aren't aware of any yet. - kernel-doc format fixes - drop ifdef fun around of_match_ptr - it's not worth the mess to save a tiny amount of space. - drop some unnecessary register initializations. - drop the weird locked gain modes as they gain us nothing (can just set all gains separately). - remove handling of offset attributes seeing as no channels actually have them (oops) - Drop the LED3 input channel as it's an alias for ALED2. - *big one* remove channel names - an experiment that turned out to not make sense - see patch for details. - use regmap fields to clean up code. - tie the tia gain stages to appropriate channels in the ABI as that is what they really effect. Same with the LED currents. - cleanout some unused defines and fix a missnamed one. * atlas-ph - reorganise to allow support of other similar parts. * bmc150 - document supported chips in kconfig help. * jsa1212 - drop an unneeded i2c functionality check for functionality the driver doesn't use. * mxs-lradc - simply touch screen registration code. - remove the touch screen unregister as all devm based now. - disable only those channels that are masked in hardware stop (others are already dealt with elsewhere) * st-sensors - unexport st_sensors_get_buffer_element as nothing outside the st-sensors core driver uses it. - fix handling of failure to start up regulators. * tpl0102 - drop an i2c functionality test for features that aren't needed. * ti-am335x - use variable name rather than type in sizeof for clarity. - use SIMPLE_DEV_PM_OPS helper macro to tidy up a bit. Tools * Add install / uninstall to makefile. Someone cares, so presumably some people will find it useful! * generic_buffer - rename to iio_generic_buffer to line up with other tools. - handle cleanup when receiving signals - Add a --device-num option and a --trigger-num option rather than relying on naming which doesn't work if you have two of the same part. -----BEGIN PGP SIGNATURE----- Version: GnuPG v2 iQIcBAABCAAGBQJXWFXGAAoJEFSFNJnE9BaIQ4kP/jcoVTR8w6EMdcr1BErrvFgm IMbMMK8wJtc1dhKcp77h/DQjCunPAaDMgdtg1uJcreRDl1dY1jiFh/PMLrt/eods tsJZcN1h40aLlPEdMQFl3oiaWjpUm23gdDtfiCHA+sM/FhQ+A+83EdonU7hbAGT2 E2NAb5xkC+74WEUit5qEouz++4JRnsJEpBx3A7mwkiUH9RnFA9OflsTdIFSIEbzb V4yMWeYBAlhwKPy/7z6/hAMK/+Psabw8FppCAw2HcADVpT517rkl4MpvErSZeFGz cr46+ZWhXZ4PaG2jG2xVLpqSbqLSfWp8uqfj0WavW2gFn/1jCB+FST904q7IPVW2 QPxALqxMAMSzOHxTYmDLfJ4IJ5vvLKroom4ixKgbl7jKXF3+PTooR6U4hGQmLK7K VKWjb/kIdHpuRT3/pG2kysMtJkk1av5BBZkl9sWUEFgCd4vYP1eB1Ah3aE/P26OH BCueMDaJqKAzmVa6Dx5MCLlJpxHpQl/OBz5wdXiMRbYeky/QHgzaTmi/HZ0wwXvn zFHAglWzLq7q0HY+q7wwI20R16cRYIve3HOaLFvQdXd1xpBP1BF+aAxT/vSb+otS 1OWCEHAxq4XEM7VcRKv9XL59gXuSB8ZaSl6k82+IjjfgOqLHh8BSygVle7iu14TE glokfXQRC7xhgfC1zQf9 =Hq1a -----END PGP SIGNATURE----- Merge tag 'iio-for-4.8a' of git://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio into staging-next Jonathan writes: First round of IIO new device support, features and cleanups for the 4.8 cycle.

First round of iio fixes for the 4.7 cycle.
A slightly bumper set due to travel delaying the pull request and a fair few issues with the recent merge window patches. Patches all over the place. The st-sensors one is probably the most involved, but definitly solves the issues seen. Note there are some other issues around that handler (and the fact that a lot of boards tie a level interrupt chip to an edge interrupt only irq chip). These are not regressions however, so will turn up the slow route. * core - iio_trigger_attach_pollfunc had some really badly wrong error handling. Another nasty triggered whilst chasing down issues with the st sensors rework below. * ad5592r - fix an off by one error when allocating channels. * am2315 - a stray mutex unlock before we ever take the lock. * apds9960 - missing a parent in the driver model (which should be the i2c device). Result is it doesn't turn up under /sys/bus/i2c/devices which some userspace code uses for repeatable device identification. * as3935 - ABI usage bug which meant a processed value was reported as raw. Now reporting scale as well to ensure userspace has the info it needs. - Don't return processed value via the buffer - it doesn't conform to the ABI and will overflow in some cases. - Fix a wrongly sized buffer which would overflow trashing part of the stack. Also move it onto the heap as part of the fix. * bh1780 - a missing return after write in debugfs lead to an incorrect read and a null pointer dereference. - dereferencing the wrong pointer in suspend and resume leading to unpredictable results. - assign a static name to avoid accidentally ending up with no name if loaded via device tree. * bmi160 - output data rate for the accelerometer was incorrectly reported. Fix it. - writing the output data rate was also wrong due to reverse parameters. * bmp280 - error message for wrong chip ID gave the wrong expected value. * hdc100x - mask for writing the integration time was wrong allowin g us to get 'stuck' in a particular value with no way back. - temperature reported in celsius rather than millicelsius as per the ABI. - Get rid of some incorrect data shifting which lead to readings being rather incorrect. * max44000 - drop scale attribute for proximity as it is an unscaled value (depends on what is in range rather than anything knowable at the detector). * st-pressure - ABI compliance fixes - units were wrong. * st-sensors - We introduced some nasty issues with the recent switch over to a a somewhat threaded handler in that we broke using a software trigger with these devices. Now do it properly. It's a larger patch than ideal for a fix, but the logic is straight forward. - Make sure the trigger is initialized before requesting the interrupt. This matters now the interrupt can be shared. Before it was ugly and wrong but short of flakey hardware could not be triggered. - Hammer down the dataready pin at boot - otherwise with really unlucky timing things could get interestingly wedged requiring a hard power down of the chip. -----BEGIN PGP SIGNATURE----- Version: GnuPG v2 iQIcBAABCAAGBQJXVxMzAAoJEFSFNJnE9BaI3QUP/2TLXJ4S+jNFSGslMmq9Ztqm fPGoyPf2nfJCzwgPFK7Yku8mFhqaRbbZrM0m1IA7hYbuZMXZjjQnSrIiDqsDuvXy 1mK3mieCu8hPFTcvVUp1q9HwrrEFIke52LIH6urSDpr1IIbhJQ2ZwXjZIJGhlukc yFwMuA7gz/akc3war+OlS1bbEOe4OuikWMP3Fc3QGKPR7C92M0S8oRyZwBmB2vqu 1lqCzS0JxL3Lz3TqDXkBd+77My7S4af/F7l8JfeCDBoE4zycASP1LUgiSD2aB3Rq hi7hrQjPCFk6rxZ+wFIyC8V0AGeGdEDpQ4JW9rgzDC/KO9Z3Wyq/h5UrQqsnZW0G xbJgLF3Wa0noh/bT0yIGZGcenM57QIJ0vTEymmikbWCNQfzqSG9a0SM7zMukB6Lr IAvMbF3Q3n/d4rzVOE5C9vRPRnG2jICxmA3EKp7blV0hRdd197J7UfN8ExG+9zC7 JxqQh5LLu76Ql7TJqQh7sZl/6Xi0DnUm+wqaxyCgtaZjmsVZ58S6G6E2eefO5Hma r3VUfthe7N0wnWwCs2RMBkBynhb7+4G11m2jp1a4PMYCYg4FhYP7QdDkeDiOSXbG s9Y1ILLI7ufzCyKf5GID7/FtAjdJahVR2ldIy7MwUqw7zAyjsm+ujIpTGZ8iYUvb whHwMtLLTnyB8Zj81LRD =EEPO -----END PGP SIGNATURE----- Merge tag 'iio-fixes-for-4.7a' of git://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio into staging-linus Jonathan writes: First round of iio fixes for the 4.7 cycle.

zram: introduce per-device debug_stat sysfs node
debug_stat sysfs is read-only and represents various debugging data that zram developers may need. This file is not meant to be used by anyone else: its content is not documented and will change any time w/o any notice. Therefore, the output of debug_stat file contains a version string. To avoid any confusion, we will increase the version number every time we modify the output. At the moment this file exports only one value -- the number of re-compressions, IOW, the number of times compression fast path has failed. This stat is temporary any will be useful in case if any per-cpu compression streams regressions will be reported.

ibft: Expose iBFT acpi header via sysfs
Some ethernet adapter vendors are supplying products which support optional (payed license) features. On some adapters this includes a hardware iscsi initiator. The same adapters in a normal (no extra licenses) mode of operation can be used as a software iscsi initiator. In addition, software iscsi boot initiators are becoming a standard part of many vendors uefi implementations. This is creating difficulties during early boot/install determining the proper configuration method for these adapters when they are used as a boot device. The attached patch creates sysfs entries to expose information from the acpi header of the ibft table. This information allows for a method to easily determining if an ibft table was created by a ethernet card's firmware or the system uefi/bios. In the case of a hardware initiator this information in combination with the pci vendor and device id can be used to ascertain any vendor specific behaviors that need to be accommodated.

dmaengine: qcom_hidma: add support for object hierarchy
In order to create a relationship model between the channels and the management object, we are adding support for object hierarchy to the drivers. This patch simplifies the userspace application development. We will not have to traverse different firmware paths based on device tree or ACPI based kernels. No matter what flavor of kernel is used, objects will be represented as platform devices. The new layout is as follows: hidmam_10: hidma-mgmt@0x5A000000 { compatible = "qcom,hidma-mgmt-1.0"; ... hidma_10: hidma@0x5a010000 { compatible = "qcom,hidma-1.0"; ... } } The hidma_mgmt_init detects each instance of the hidma-mgmt-1.0 objects in device tree and calls into the channel driver to create platform devices for each child of the management object.

iio: health/afe440x: Make gain settings a modifier for the stages
Currently the TIA gain settings are exported to userspace as sysfs entries that do not clearly represent their internal relation to the sampling stages. The gain settings are enabled on a per-stage basis, this can be seen in figure 24 of the current AFE4404 datasheet. These gain settings should therefore be tied to the channels that are read during these stages. Make this change here. Signed-off-by: Andrew F.

iio: health/afe440x: Remove channel names
These AFEs have 4 ADC mesuring stages (called LED2, ALED2, LED1, and ALED1 in the datasheet), we map these as channels, these stages can serve different purposes depending on the application. For instance the AFE4404 has an additional LED (LED3), this LED can be timed to be active during stage 2 (or anystage, but the datasheet describes this case and the name of the stage reflects this use). This ability is used further in upcoming parts that tie the front-end gain and the LED timings together. For these reasons we remove explicit naming the channels. Without channel names it is best that the index numbers are in order to match the stage number, reorder the channel numbers. Signed-off-by: Andrew F.

Bit of a bumper set for new drivers but plenty of other stuff here as well! New device support * ad5592R ADC/DAC - new driver supporting ad5592r and ad5593r combined ADC/DAC and gpio chips. * Aosong am2315 relative humidity - new driver with triggered buffer support in follow up patch. * bmi160 imu - new driver * bmp280 - bmp180 support - note there is support in the misc/bmp085 driver. Intent is to remove that driver long term. * invensense mpu6050 - cleanup leading to explicit support of mpu9150 with a good few cleanups along the way. * Hope RF hp03 pressure and temperature sensor. - new driver * maxim DS1803 potentiometer - new driver * maxim max44000 light and proximity sensor - new driver built in a series of steps to support pretty much everything. * ROHM BH1780 light sensor - new driver. There is an existing driver in misc that this is pretty much intended to replace.

iio:imu:mpu6050: enhance mounting matrix support
Add a new rotation matrix sysfs attribute compliant with IIO core mounting matrix API. Matrix is retrieved from "in_anglvel_mount_matrix" and "in_accel_mount_matrix" sysfs attributes. It is declared into mpu6050 DTS entry as a "mount-matrix" property. Old interface is kept for backward userspace compatibility and may be retrieved from legacy platform_data mechanism only.

iio:core: mounting matrix support
Expose a rotation matrix to indicate userspace the chip placement with respect to the overall hardware system. This is needed to adjust coordinates sampled from a sensor chip when its position deviates from the main hardware system. Final coordinates computation is delegated to userspace since: * computation may involve floating point arithmetics ; * it allows an application to combine adjustments with arbitrary transformations. This 3 dimentional space rotation matrix is expressed as 3x3 array of strings to support floating point numbers. It may be retrieved from a "[<dir>_][<type>_]mount_matrix" sysfs attribute file. It is declared into a device / driver specific DTS property or platform data. Signed-off-by: Gregor Boirie <gregor.boirie@parrot.com> Signed-off-by: Jonathan Cameron <jic23@kernel.org> |

cxl: Allow initialization on timebase sync failures
Failure to synchronize the PSL timebase currently prevents the initialization of the cxl card, thus rendering the card useless. This is too extreme for a feature which is rarely used, if at all. No hardware AFUs or software is currently using PSL timebase. This patch still tries to synchronize the PSL timebase when the card is initialized, but ignores the error if it can't. Instead, it reports a status via /sys. Signed-off-by: Frederic Barrat <fbarrat@linux.vnet.ibm.com> Acked-by: Ian Munsie <imunsie@au1.ibm.com> Signed-off-by: Michael Ellerman <mpe@ellerman.id.au> |

Specifics: - Fix for an intel_pstate driver issue related to the handling of MSR updates uncovered by the recent cpufreq rework (Rafael Wysocki). - cpufreq core cleanups related to starting governors and frequency synchronization during resume from system suspend and a locking fix for cpufreq_quick_get() (Rafael Wysocki, Richard Cochran). - acpi-cpufreq and powernv cpufreq driver updates (Jisheng Zhang, Michael Neuling, Richard Cochran, Shilpasri Bhat). - intel_idle driver update preventing some Skylake-H systems from hanging during initialization by disabling deep C-states mishandled by the platform in the problematic configurations (Len Brown). - Intel Xeon Phi Processor x200 support for intel_idle (Dasaratharaman Chandramouli). - cpuidle menu governor updates to make it always honor PM QoS latency constraints (and prevent C1 from being used as the fallback C-state on x86 when they are set below its exit latency) and to restore the previous behavior to fall back to C1 if the next timer event is set far enough in the future that was changed in 4.4 which led to an energy consumption regression (Rik van Riel, Rafael Wysocki). - New device ID for a future AMD UART controller in the ACPI driver for AMD SoCs (Wang Hongcheng). - Rockchip rk3399 support for the rockchip-io-domain adaptive voltage scaling (AVS) driver (David Wu). - ACPI PCI resources management fix for the handling of IO space resources on architectures where the IO space is memory mapped (IA64 and ARM64) broken by the introduction of common ACPI resources parsing for PCI host bridges in 4.4 (Lorenzo Pieralisi). - Fix for the ACPI backend of the generic device properties API to make it parse non-device (data node only) children of an ACPI device correctly (Irina Tirdea). - Fixes for the handling of global suspend flags (introduced in 4.4) during hibernation and resume from it (Lukas Wunner). - Support for obtaining configuration information from Device Trees in the PM clocks framework (Jon Hunter). - ACPI _DSM helper code and devfreq framework cleanups (Colin Ian King, Geert Uytterhoeven)" * tag 'pm+acpi-4.6-rc1-2' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: (23 commits) PM / AVS: rockchip-io: add io selectors and supplies for rk3399 intel_idle: Support for Intel Xeon Phi Processor x200 Product Family intel_idle: prevent SKL-H boot failure when C8+C9+C10 enabled ACPI / PM: Runtime resume devices when waking from hibernate PM / sleep: Clear pm_suspend_global_flags upon hibernate cpufreq: governor: Always schedule work on the CPU running update cpufreq: Always update current frequency before startig governor cpufreq: Introduce cpufreq_update_current_freq() cpufreq: Introduce cpufreq_start_governor() cpufreq: powernv: Add sysfs attributes to show throttle stats cpufreq: acpi-cpufreq: make Intel/AMD MSR access, io port access static PCI: ACPI: IA64: fix IO port generic range check ACPI / util: cast data to u64 before shifting to fix sign extension cpufreq: powernv: Define per_cpu chip pointer to optimize hot-path cpuidle: menu: Fall back to polling if next timer event is near cpufreq: acpi-cpufreq: Clean up hot plug notifier callback intel_pstate: Do not call wrmsrl_on_cpu() with disabled interrupts cpufreq: Make cpufreq_quick_get() safe to call ACPI / property: fix data node parsing in acpi_get_next_subnode() ACPI / APD: Add device HID for future AMD UART controller ... |

Merge branch 'i2c/for-next' of git://git.kernel.org/pub/scm/linux/kernel/git/wsa/linux
Pull i2c updates from Wolfram Sang: "Mostly usual driver updates and improvements. The changelog should give an idea. Standing out is the i2c-qup driver with lots of new capabilities and we also have now an i2c-demuxer. I'd especially like to welcome Peter Rosin as the i2c-mux maintainer. He has an interesting series for muxes in the queue and agreed to look after this part of the subsystem. Thank you, Peter, and welcome again! The octeon changes were applied pretty recently before the merge window. I am aware. They are the first (and relatively simple) patches of a larger overhaul to this driver. In case something goes wrong with them, they are easy to fix (or revert). The advantage I see is that they are out of the way, and I can concentrate on the next block of patches. I really would like to apply the overhaul in smaller batches to avoid regressions.
