Marek Szyprowski 726b6324e3 mmc: pwrseq: add driver for emmc hardware reset
This patch provides a simple mmc-pwrseq-emmc driver, which controls
single gpio line. It perform standard eMMC hw reset procedure, as
descibed by Jedec 4.4 specification. This procedure is performed just
after MMC core enabled power to the given mmc host (to fix possible
issues if bootloader has left eMMC card in initialized or unknown
state), and before performing complete system reboot (also in case of
emergency reboot call). The latter is needed on boards, which doesn't
have hardware reset logic connected to emmc card and (limited or broken)
ROM bootloaders are unable to read second stage from the emmc card if
the card is left in unknown or already initialized state.

Paul Walmsley 10638a4ed2 Documentation: DT: document compatible string existence requirement
DT maintainers require all compatible strings used in chip or board
DTS file to be previously documented somewhere in
Documentation/devicetree/bindings, per:

http://marc.info/?l=linux-tegra&m=142201349727836&w=2

Document this requirement in the DT patch submission requirements

Paul Walmsley f634da375f Documentation: DT bindings: add nvidia, tegra132-denver compatible string
Add a compatible string for the NVIDIA Denver CPU to the ARM CPU DT
binding documentation file.  The primary objective here is to keep
checkpatch.pl from warning when the compatible string is used in an
SoC DT file, per:

http://marc.info/?l=linux-tegra&m=142201349727836&w=2

This second version changes the string from "nvidia,denver" to
"nvidia,tegra132-denver" to more precisely describe the revision of
the Denver CPU complex that is present in the Tegra132 SoC.

Paul Walmsley 193c9d23a0 Documentation: DT bindings: add more Tegra chip compatible strings
Align compatible strings for several IP blocks present on Tegra chips
with the latest doctrine from the DT maintainers:

http://marc.info/?l=devicetree&m=142255654213019&w=2

The primary objective here is to avoid checkpatch warnings, per:

http://marc.info/?l=linux-tegra&m=142201349727836&w=2

DT binding text files have been updated for the following IP blocks:

- PCIe
- SOR
- SoC timers
- AHB "gizmo"
- APB_MISC
- pinmux control
- UART
- PWM
- I2C
- SPI
- RTC
- PMC
- eFuse
- AHCI
- HDA
- XUSB_PADCTRL
- SDHCI
- SOC_THERM
- AHUB
- I2S
- EHCI
- USB PHY

N.B. The nvidia,tegra20-timer compatible string is removed from the
nvidia,tegra30-timer.txt documentation file because it's already
mentioned in the nvidia,tegra20-timer.txt documentation file.

This second version takes into account the following requests from
Rob Herring <robherring2@gmail.com>:

- Per-IP block patches have been combined into a single patch

- Explicit documentation about which compatible strings are actually
  matched by the driver has been removed.  In its place is implicit
  documentation that loosely follows Rob's prescribed format:

  "Must contain '"nvidia,<chip>-pcie", "nvidia,tegra20-pcie"' where
   <chip> is tegra30, tegra132, ..." [...]  "You should attempt to
   document known values of <chip> if you use it"

Willem de Bruijn b245be1f4d net-timestamp: no-payload only sysctl
Tx timestamps are looped onto the error queue on top of an skb. This
mechanism leaks packet headers to processes unless the no-payload
options SOF_TIMESTAMPING_OPT_TSONLY is set.

Add a sysctl that optionally drops looped timestamp with data. This
only affects processes without CAP_NET_RAW.

The policy is checked when timestamps are generated in the stack.
It is possible for timestamps with data to be reported after the
sysctl is set, if these were queued internally earlier.

No vulnerability is immediately known that exploits knowledge
gleaned from packet headers, but it may still be preferable to allow
administrators to lock down this path at the cost of possible
breakage of legacy applications.

Changes
  (v1 -> v2)
  - test socket CAP_NET_RAW instead of capable(CAP_NET_RAW)
  (rfc -> v1)
  - document the sysctl in Documentation/sysctl/net.txt
  - fix access control race: read .._OPT_TSONLY only once,
        use same value for permission check and skb generation.

Willem de Bruijn 49ca0d8bfa net-timestamp: no-payload option
Add timestamping option SOF_TIMESTAMPING_OPT_TSONLY. For transmit
timestamps, this loops timestamps on top of empty packets.

Doing so reduces the pressure on SO_RCVBUF. Payload inspection and
cmsg reception (aside from timestamps) are no longer possible. This
works together with a follow on patch that allows administrators to
only allow tx timestamping if it does not loop payload or metadata.

Peter Griffin bbd3ce86c7 phy: miphy365x: Pass sysconfig register offsets via syscfg dt property.
Based on Arnds review comments here https://lkml.org/lkml/2014/11/13/161,
update the miphy365 phy driver to access sysconfig register offsets via
syscfg dt property.

This is because the reg property should not be mixing address spaces
like it does currently for miphy365. This change then also aligns us
to how other platforms such as keystone and bcm7445 pass there syscon
offsets via DT.

This patch breaks DT compatibility, but this platform is considered WIP,
and is only used by a few developers who are upstreaming support for it.
This change has been done as a single atomic commit to ensure it is
bisectable.

Sylwester Nawrocki e4b3d38088 phy: exynos-video-mipi: Fix regression by adding support for PMU regmap
After the Exynos Power Management Unit (PMU) driver was converted
to the platform device driver in commit 14fc8b93d4
("ARM: EXYNOS: Add platform driver support for Exynos PMU") and
then PMU device nodes added to Exynos4 DTs in commit
7b9613aca4 ("ARM: dts: add PMU syscon node for exynos4")
the mipi video phy driver started failing probing, due to overlapping
memory mapped register region resources.

Now all the Exynos peripheral devices which have registers in the PMU
region are supposed to use the regmap provided by the syscon driver.
So support for regmap is added in this patch, this unfortunately
creates yet another indirection into that supposedly trivial driver.

The additional mutex is required because single register is used by
PHY pairs (they share bit in a register). An improvement here could
be to allow a PHY instance be created with a driver custom mutex,
which would then be common for each PHY pair. This would eliminate
one of 3 mutexes which need to be taken in the phy_power_on/
phy_power_off code path. However, I tried to keep this bug fix patch
possibly simple.

This change is needed to make MIPI DSI displays and MIPI CSI-2
camera sensors working again on Exynos4 boards.

transmit support.

Note this commits also adds checking for the end-of-packet interrupt flag
(which was already enabled), as the fifo-data-available interrupt flag only
gets set when the trigger-level is exceeded. So far we've been getting away
with not doing this because of the low trigger-level, but this is something
which we should have done since day one.

Irina Tirdea 2f0ecb7c65 iio: core: Introduce IIO_CHAN_INFO_DEBOUNCE_COUNT and _TIME
The pedometer needs to filter out false steps that might be generated by
tapping the foot, sitting, etc. To do that it computes the number of
steps that occur in a given time and decides the user is moving only
if this value is over a threshold. E.g.: the user starts moving only
if he takes 4 steps in 3 seconds. This filter is applied only when
the user starts moving.

A device that has such pedometer functionality is Freescale's MMA9553L:
http://www.freescale.com/files/sensors/doc/ref_manual/MMA9553LSWRM.pdf.

To export this feature, this patch introduces IIO_CHAN_INFO_DEBOUNCE_COUNT
and IIO_CHAN_INFO_DEBOUNCE_TIME. For the pedometer, in_steps_debounce_count
will specify the number of steps that need to occur in
in_steps_debounce_time seconds so that the pedometer decides the user is
moving.

Baruch Siach 9ff99be7dc clocksource: devicetree: Document Conexant Digicolor timer binding
The Conexant CX92755 SoC provides 8 32-bit timers as part of its so called
"Agent Communication" block. Timers can be configures either as free running or
one shot. Each timer has a dedicated interrupt source in the CX92755 interrupts
controller. The first timer (Timer A) can also be configured as watchdog.

This commit adds devicetree binding definition of this hardware module. The
binding defined here should be reusable for other SoCs in the Digicolor series.

Daniel Lezcano 468b8c4cf3 clockevents: rockchip: Add rockchip timer for rk3288
The rk3288 board uses the architected timers and these ones are shutdown when
the cpu is powered down. There is a need of a broadcast timer in this case to
ensure proper wakeup when the cpus are in sleep mode and a timer expires.

This driver provides the basic timer functionnality as a backup for the local
timers at sleep time.

The timer belongs to the alive subsystem. It includes two programmables 64 bits
timer channels but the driver only uses 32bits. It works with two operations
mode: free running and user defined count.

Programing sequence:

1. Timer initialization:
 * Disable the timer by writing '0' to the CONTROLREG register
 * Program the timer mode by writing the mode to the CONTROLREG register
 * Set the interrupt mask

2. Setting the count value:
 * Load the count value to the registers COUNT0 and COUNT1 (not used).

3. Enable the timer
 * Write '1' to the CONTROLREG register with the mode (free running or user)

Peter Rosin f086ba9d53 ASoC: pcm512x: Support mastering BCLK/LRCLK using the PLL
Using the PLL in master mode requires using an external connection
between one of the GPIO pins (configured as PLL/4 output) and the
SCK pin. It also requires the external clock to be fed to some other
GPIO pin instead of the SCK pin.

This is described for the PCM5122 chip in the answers to the forum post
"PCM5122 DAC as I2S master troubles with PLL mode" at the TI E2E
community pages (1). The clocking functionality is also much better
described in the datasheet for the chip PCM5242, which seems to be
register compatible with PCM512x and PCM514x (which both have severely
lacking datasheets).

Ingo Molnar 772a9aca12 This is my accumulated x86 entry work, part 1, for 3.20. The meat
of this is an IST rework.  When an IST exception interrupts user
 space, we will handle it on the per-thread kernel stack instead of
 on the IST stack.  This sounds messy, but it actually simplifies the
 IST entry/exit code, because it eliminates some ugly games we used
 to play in order to handle rescheduling, signal delivery, etc on the
 way out of an IST exception.
 
 The IST rework introduces proper context tracking to IST exception
 handlers.  I haven't seen any bug reports, but the old code could
 have incorrectly treated an IST exception handler as an RCU extended
 quiescent state.
 
 The memory failure change (included in this pull request with
 Borislav and Tony's permission) eliminates a bunch of code that
 is no longer needed now that user memory failure handlers are
 called in process context.
 
 Finally, this includes a few on Denys' uncontroversial and Obviously
 Correct (tm) cleanups.

Ulf Hansson 0e6d633274 mmc: pwrseq: Document DT bindings for the simple MMC power sequence
To support SOCs which specifies specific MMC power sequences, document
some MMC DT bindings to be able to describe these hardwares.

Let's also document bindings for a simple MMC power sequence provider,
which purpose is to support a set of common properties between various
SOCs.

In this initial step, let's also document a top level description of
the MMC power sequence and describe the compatible string used for the
simple MMC power sequence provider.

The simple MMC power sequence provider will initially support a reset
GPIO. From several earlier posted patches, it's clear that such
hardware exists. Especially some WLAN chips which are attached to an
SDIO interface may use a GPIO reset.

This patch adds support for the GiantPlus GPG48273QS5 4.3" WQVGA TFT LCD
panel to the simple-panel driver.

This panel is connected via a parallel bus and uses both HSYNC and
VSYNC, whose lengths are unfortunately not clearly defined. The
datasheet only specifies the front- and backporch length, but the timing
diagram suggests that both sync signals should be asserted for exactly
one clock cycle.

not to rebase. But I'll pay close attention to this in the future to

patchwork.kernel.org, the latest patchwork doesn't seem to have this
bug.

Also please note this pull request also adds one DT binding doc, but
this was reviewed in the device tree list:

Joe Stringer 74ed7ab926 openvswitch: Add support for unique flow IDs.
Previously, flows were manipulated by userspace specifying a full,
unmasked flow key. This adds significant burden onto flow
serialization/deserialization, particularly when dumping flows.

This patch adds an alternative way to refer to flows using a
variable-length "unique flow identifier" (UFID). At flow setup time,
userspace may specify a UFID for a flow, which is stored with the flow
and inserted into a separate table for lookup, in addition to the
standard flow table. Flows created using a UFID must be fetched or
deleted using the UFID.

All flow dump operations may now be made more terse with OVS_UFID_F_*
flags. For example, the OVS_UFID_F_OMIT_KEY flag allows responses to
omit the flow key from a datapath operation if the flow has a
corresponding UFID. This significantly reduces the time spent assembling
and transacting netlink messages. With all OVS_UFID_F_OMIT_* flags
enabled, the datapath only returns the UFID and statistics for each flow
during flow dump, increasing ovs-vswitchd revalidator performance by 40%
or more.

Liviu Dudau fb7e7deb7f irqchip: gic: Allow interrupt level to be set for PPIs
During a recent cleanup of the arm64 DTs it has become clear that
the handling of PPIs in xxxx_set_type() is incorrect. The ARM TRMs
for GICv2 and later allow for "implementation defined" support for
setting the edge or level type of the PPI interrupts and don't restrict
the activation level of the signal. Current ARM implementations
do restrict the PPI level type to IRQ_TYPE_LEVEL_LOW, but licensees
of the IP can decide to shoot themselves in the foot at any time.

Magnus Damm e03f9088e2 irqchip: renesas-intc-irqpin: r8a7779 IRLM setup support
Add r8a7779 specific support for IRLM bit configuration
in the INTC-IRQPIN driver. Without this code we need
special workaround code in arch/arm/mach-shmobile.

The IRLM bit for the INTC hardware exists on various
older SH-based SoCs and is used to select between two
modes for the external interrupt pins IRQ0 to IRQ3:

IRLM = 0: (default from reset on r8a7779)
In this mode the pins IRQ0 to IRQ3 are used together
to give a value between 0 and 15 to the SoC. External
logic is required for masking. This mode is not
supported by the INTC-IRQPIN driver.

IRLM = 1: (needs this patch or configuration elsewhere)
In this mode IRQ0 to IRQ3 operate as 4 individual
external interrupt pins. In this mode the SMSC ethernet
chip can be used via IRQ1 on r8a7779 Marzen. This mode
is the only supported mode by the INTC-IRQPIN driver.

For this patch to work the r8a7779 DTS needs to pass
the ICR0 register as the last register bank.

Harout Hedeshian c2943f1453 net: ipv6: Add sysctl entry to disable MTU updates from RA
The kernel forcefully applies MTU values received in router
advertisements provided the new MTU is less than the current. This
behavior is undesirable when the user space is managing the MTU. Instead
a sysctl flag 'accept_ra_mtu' is introduced such that the user space
can control whether or not RA provided MTU updates should be applied. The
default behavior is unchanged; user space must explicitly set this flag
to 0 for RA MTUs to be ignored.

Pull platform driver fix from Darren Hart:
 "Revert keyboard backlight sysfs support and documentation.

  The support for the dell-laptop keyboard backlight was flawed and the
  fix:

        https://lkml.org/lkml/2015/1/14/539

  was more invasive that I felt comfortable sending at RC5.

  This series reverts the support for the dell-laptop keyboard backlight

Suzuki K. Poulose 2d888f48e0 arm64: Emulate SETEND for AArch32 tasks
Emulate deprecated 'setend' instruction for AArch32 bit tasks.

	setend [le/be] - Sets the endianness of EL0

On systems with CPUs which support mixed endian at EL0, the hardware
support for the instruction can be enabled by setting the SCTLR_EL1.SED
bit. Like the other emulated instructions it is controlled by an entry in
/proc/sys/abi/. For more information see :
	Documentation/arm64/legacy_instructions.txt

The instruction is emulated by setting/clearing the SPSR_EL1.E bit, which
will be reflected in the PSTATE.E in AArch32 context.

This patch also restores the native endianness for the execution of signal
handlers, since the process could have changed the endianness.

Note: All CPUs on the system must have mixed endian support at EL0. Once the
handler is registered, hotplugging a CPU which doesn't support mixed endian,
could lead to unexpected results/behavior in applications.

 A recent change can cause KVM hangs if adjtime is used in the host.
 The hrtimer might wake up too early or too late. Too early is fatal
 as vcpu_block will see that the wakeup condition is not met and
 sleep again. This CPU might never wake up again.
 This series addresses this problem. adjclock slowing down the host
 clock will result in too late wakeups. This will require more work.
 In addition to that we also change the hrtimer from REALTIME to
 MONOTONIC to avoid similar problems with timedatectl set-time.
 
 3. sigp rework
 We will move all "slow" sigps to QEMU (protected with a capability that
 can be enabled) to avoid several races between concurrent SIGP orders.
 
 4. Optimize the shadow page table
 Provide an interface to announce the maximum guest size. The kernel
 will use that to make the pagetable 2,3,4 (or theoretically) 5 levels.
 
 5. Provide an interface to set the guest TOD
 We now use two vm attributes instead of two oneregs, as oneregs are
 vcpu ioctl and we don't want to call them from other threads.
 
 6. Protected key functions

 Lets provide an implementation + an interface for QEMU to activate

David Hildenbrand 2444b352c3 KVM: s390: forward most SIGP orders to user space
Most SIGP orders are handled partially in kernel and partially in
user space. In order to:
- Get a correct SIGP SET PREFIX handler that informs user space
- Avoid race conditions between concurrently executed SIGP orders
- Serialize SIGP orders per VCPU

We need to handle all "slow" SIGP orders in user space. The remaining
ones to be handled completely in kernel are:
- SENSE
- SENSE RUNNING
- EXTERNAL CALL
- EMERGENCY SIGNAL
- CONDITIONAL EMERGENCY SIGNAL
According to the PoP, they have to be fast. They can be executed
without conflicting to the actions of other pending/concurrently
executing orders (e.g. STOP vs. START).

This patch introduces a new capability that will - when enabled -
forward all but the mentioned SIGP orders to user space. The
instruction counters in the kernel are still updated.

Dominik Dingel 8c0a7ce606 KVM: s390: Allow userspace to limit guest memory size
With commit c6c956b80b ("KVM: s390/mm: support gmap page tables with less
than 5 levels") we are able to define a limit for the guest memory size.

As we round up the guest size in respect to the levels of page tables
we get to guest limits of: 2048 MB, 4096 GB, 8192 TB and 16384 PB.
We currently limit the guest size to 16 TB, which means we end up
creating a page table structure supporting guest sizes up to 8192 TB.

This patch introduces an interface that allows userspace to tune
this limit. This may bring performance improvements for small guests.

Ryan Grimm 62fa19d4b4 cxl: Add ability to reset the card
Adds reset to sysfs which will PERST the card. If load_image_on_perst is set
to "user" or "factory", the PERST will cause that image to be loaded.

load_image_on_perst is set to "user" for production.

"none" could be used for debugging. The PSL trace arrays are preserved which
then can be read through debugfs.

PERST also triggers CAPP recovery. An HMI comes in, which is handled by EEH.
EEH unbinds the driver, calls into Sapphire to reinitialize the PHB, then
rebinds the driver.

load_image_on_perst identifies whether a PERST will cause the image to be
flashed to the card. And if so, which image.

Valid entries are: "none", "user" and "factory".

A value of "none" means PERST will not cause the image to be flashed. A
power cycle to the pcie slot is required to load the image.

"user" loads the user provided image and "factory" loads the factory image upon
PERST.

sysfs updates the cxl struct in the driver then calls cxl_update_image_control
to write the vals in the VSEC.

Cody P Schafer 98a43e0e99 perf Documentation: Add event parameters
Event parameters are a basic way for partial events to be specified in
sysfs with per-event names given to the fields that need to be filled in
when using a particular event.

It is intended for supporting cases where the single 'cpu' parameter is
insufficient. For example, POWER 8 has events for physical
sockets/cores/cpus that are accessible from with virtual machines. To
keep using the single 'cpu' parameter we'd need to perform a mapping
between Linux's cpus and the physical machine's cpus (in this case Linux
is running under a hypervisor). This isn't possible because bindings
between our cpus and physical cpus may not be fixed, and we probably
won't have a "cpu" on each physical cpu.

Peter Griffin 5402d927ae phy: phy-stih407-usb: Pass sysconfig register offsets via syscfg property.
Based on Arnds review comments here https://lkml.org/lkml/2014/11/13/161,
update the phy driver to not use the reg property to access the sysconfig
register offsets.

This is because other phy's (miphy28, miphy365) have a combination of
memory mapped registers and sysconfig control regs, and we shouldn't
be mixing address spaces in the reg property. In addition we would
ideally like the sysconfig offsets to be passed via DT in a uniform way.

This new method will also allow us to support devices which have sysconfig
registers in different banks more easily and it is also analagous to how
keystone and bcm7745 platforms pass there syscon offsets in DT.

This breaks DT compatibility, but this platform is considered WIP, and
is only used by a few developers who are upstreaming support for it.

Based on Arnds review comments here https://lkml.org/lkml/2014/11/13/161,
update the miphy28lp phy driver to access sysconfig register offsets via
syscfg dt property.

This is because the reg property should not be mixing address spaces like
it does currently for miphy28lp. This change then also aligns us to how other
platforms such as keystone and bcm7445 pass there syscon offsets via DT.

I have updated the miphy28lp phy driver same way as Peter's implementation.

Boris Brezillon 5b7e944ec8 drm: add DT bindings documentation for atmel-hlcdc-dc driver
The Atmel HLCDC (HLCD Controller) IP available on some Atmel SoCs (i.e.
at91sam9n12, at91sam9x5 family or sama5d3 family) provides a display
controller device.

The HLCDC block provides a single RGB output port, and only supports LCD
panels connection to LCD panels for now.

The atmel,panel property link the HLCDC RGB output with the LCD panel
connected on this port (note that the HLCDC RGB connector implementation
makes use of the DRM panel framework).

Connection to other external devices (DRM bridges) might be added later by
mean of a new atmel,xxx (atmel,bridge) property.

Greg Kroah-Hartman 6e49557b31 First round of IIO new drivers, cleanups and functionality for the 3.20 cycle take 2
Updated pull request with Daniel's fix on top for the power management
 Kconfig changes that had snuck in since last update of the IIO tree
 worked it's way through from mainline.
 
 Original pull message
 
 New device support
 * jsa1212 proxmity / ambient light sensor
 * SM08500 supported added to the kxcjk-1013 accelerometer driver
 * KMX61 Accelerometer/Magnetometer.  This took a somewhat rocky path
   being first merged, then reverted for a rewrite after a discussion of
   how to support additional functionality and finally being merged prior
   to some last reviews coming in, with resultant follow up patches.
 * Freescale mma9551l driver (minor follow up warning supression patch).
 * Semtech SX9500 proximity device driver.
 * ak8975 gains support for ak09911 and ak09912 and drop the standalone driver
   for the ak09911.
 
 New functionality
  * Dummy driver gains some virtual registers making it more flexible.
  * IIO_ACTIVITY channel types, with modifiers running, walking etc.  This is
    to support on chip motion clasifiers.  As such it is in the form of a
    confidence percentage.  The only devices so far only do binary decisions
    but this gives us room when other devices give more nuanced clasification.
  * IIO_EV_DIR_NONE type for events where there is no obvious direction.
    First case is step detection.
  * IIO_STEPS channel type for pedometers.
  * ENABLE mask element used to control turning on counting types such as
    the pedometer that need a 'start point'.
  * INSTANCE event type to support things that happen once.
  * info element for height calibration (used in various motion estimation
    algorithms). Note heigh tof use
  * dummy driver demonstration of the use of all the new bits above.
  * event monitor support for the new events.
  * inv_mpu6050 gains an i2c mux to allow bypassing the device to access
    additional devices connected on the other side of it.  Note that in
    Windows these are handled by firmware on the device and not exposed
    directly.
  * inv_mpu6050 gains ACPI enumeration.
  * inkern interface gains iio_write_channel_raw to allow in kernel users
    of DAC functionality via a simple wrapper.
  * Document input current readings in the ABI docs.
  * Add an error message when we get an out of range error in device tree
    processing for the in kernel interfaces.  Basically a device tree debugging
    aid.
  * Add a sanity check that a scan index for a channel is unique during
    registration.  There to help catch bugs as this should never happen
    in a bug free driver.
 
 Cleanups and fixlets
 
  A rework of buffer registration from Lars - a precursor to some other
  upcoming new stuff (a few patches from others rolled in here as well).
  * Ensure all drivers register the same channels for the device and buffer.
  * Move buffer registration into the core rather than using the old
    two step approach.  Now we have simple ways of using a unified set channels
    for both without requiring channels be exposed by both interface, this
    removes a fair bit of boilerplate.
  * Stop sca3000 and ad5933 (both in staging) enabling buffer channels by
    default. It has long be convention in IIO to startup with no channels
    enabled and leave it up to userspace to say what goes in the buffer.
    Getting rid of these allows us to drop export of iio_scan_mask_set.
  * Drop get_bytes_per_datum from iio_buffer_access_funcs as not been used
    for a while.
  * Allocate standard buffer attributes in the core rather than in every
    driver with a buffer.
  * Make the length attribute read only when a driver is not able to set
    the length.
  * Drop the get_length callback for buffers as it is already available in
    struct iio_buffer.
  * Drop an unused arguement form iio_kfifo_allocate and add devm allocator
    for it.
  * some kconfig entries gain anotation with the resulting module name.
  * Fix a resulting compile issue in dummy driver due to a stub taking
    wrong parameters as a result of the above rework.
  * Fix an off by 2 error in copying the core assigned buffer attributes.
 
 Other cleanups,
  * Trivial space before comma fixups.
  * ak8975 fixlets - none critical.  Rework to allow more device support.
  * Drop unnecessary sizeof(u8) calls.
  * bmp280 - refactor the compensation code to reduce copy operations and
    code length.  A second patch futher optimized this and performed some
    other minor cleanups.
  * kxcjk-1013 - various power control cleanups to avoid unnecessary enable
    / disable of device.  Make sure it is only controlled at all if CONFIG_PM
    is enabled.  Also som cleanups of error paths.
  * Small cleanups in adf4530 driver - pointless message and unnecessary braces.
  * Clarifiy the proximity ABI docs to make it clear it should get bigger
    as we move futher away.
  * Drop a misleading comment form industrialio-core.c
  * Trivial white space cleanups.
  * sca3000 looses an unused debug function.
  * Fix char unsigned ordering in ad8366
  * Increase the sleep time in ad9523 to make it predictable (value didn't
    really matter so make it more than 20 msecs)
  * mxs-lradc touchscreen property cleanups in device tree are fixed to ensure
    the meet all the 'interesting' documentation.
  * A couple of cleanups for the staging ad5933 driver to avoid unnecessary
    conversion to a processed temperature vlaue in kernel and remove
    platform data form the state structure as not needed after probe.
  * Fix a wrong scale factor in the docs.

Christoph Hellwig b4caecd480 fs: introduce f_op->mmap_capabilities for nommu mmap support
Since "BDI: Provide backing device capability information [try #3]" the
backing_dev_info structure also provides flags for the kind of mmap
operation available in a nommu environment, which is entirely unrelated
to it's original purpose.

Introduce a new nommu-only file operation to provide this information to
the nommu mmap code instead.  Splitting this from the backing_dev_info
structure allows to remove lots of backing_dev_info instance that aren't
otherwise needed, and entirely gets rid of the concept of providing a
backing_dev_info for a character device.  It also removes the need for
the mtd_inodefs filesystem.

Tony Lindgren 163152cbbe clk: ti: Add support for FAPLL on dm816x
On dm816x the clocks are sourced from a FAPLL (Flying Adder PLL)
that does not seem to be used on the other omap variants.

There are four instances of the FAPLL on dm816x that each have three
to seven child synthesizers.

I've set up the FAPLL as a single fapll.c driver. Later on we could
potentially have the PLL code generic. To do that, we would have to
consider the following:

1. Setting the PLL to bypass mode also sets the child synthesizers
   into bypass mode. As the bypass rate can also be generated by
   the PLL in regular mode, there's no way for the child synthesizers
   to detect the bypass mode based on the parent clock rate.

2. The PLL registers control the power for each of the child
   syntheriser.

Note that the clocks are currently still missing the set_rate
implementation so things are still running based on the bootloader
values. That's OK for now as most of the outputs have dividers and
those can be set using the existing TI component clock code.

I have verified that the extclk rates are correct for a few clocks,
so adding the set_rate support should be fairly trivial later on.

This code is partially based on the TI81XX-LINUX-PSP-04.04.00.02
patches published at:

Andre Przywara 4fa96afd94 arm/arm64: KVM: force alignment of VGIC dist/CPU/redist addresses
Although the GIC architecture requires us to map the MMIO regions
only at page aligned addresses, we currently do not enforce this from
the kernel side.
Restrict any vGICv2 regions to be 4K aligned and any GICv3 regions
to be 64K aligned. Document this requirement.

Andre Przywara ac3d373564 arm/arm64: KVM: allow userland to request a virtual GICv3
With all of the GICv3 code in place now we allow userland to ask the
kernel for using a virtual GICv3 in the guest.
Also we provide the necessary support for guests setting the memory
addresses for the virtual distributor and redistributors.
This requires some userland code to make use of that feature and
explicitly ask for a virtual GICv3.
Document that KVM_CREATE_IRQCHIP only works for GICv2, but is
considered legacy and using KVM_CREATE_DEVICE is preferred.

Chen-Yu Tsai 7a6fca879f clk: sunxi: Add driver for A80 MMC config clocks/resets
On the A80 SoC, the 4 mmc controllers each have a separate register
controlling their register access clocks and reset controls. These
registers in turn share a ahb clock gate and reset control.

This patch adds a platform device driver for these controls. It
requires both clocks and reset controls to be available, so using
CLK_OF_DECLARE might not be the best way.

Karicheri, Muralidharan 44eefcdfb9 Documentation: dt: net: Add binding doc for Keystone NetCP ethernet driver
The network coprocessor (NetCP) is a hardware accelerator that processes
Ethernet packets. NetCP has a gigabit Ethernet (GbE) subsystem with a ethernet
switch sub-module to send and receive packets. NetCP also includes a packet
accelerator (PA) module to perform packet classification operations such as
header matching, and packet modification operations such as checksum
generation. NetCP can also optionally include a Security Accelerator(SA)
capable of performing IPSec operations on ingress/egress packets.

Keystone SoC's also have a 10 Gigabit Ethernet Subsystem (XGbE) which
includes a 3-port Ethernet switch sub-module capable of 10Gb/s and
1Gb/s rates per Ethernet port.

NetCP Subsystem device tree layout looks something like below:

-----------------------------
  NetCP subsystem(10G or 1G)
-----------------------------
	|
	|-> NetCP Devices ->	|
	|			|-> GBE/XGBE Switch
	|			|
	|			|-> Packet Accelerator
	|			|
	|			|-> Security Accelerator
	|
	|
	|
	|-> NetCP Interfaces ->	|
				|-> Ethernet Port 0
				|
				|-> Ethernet Port 1
				|
				|-> Ethernet Port 2
				|
				|-> Ethernet Port 3

Common driver supports GBE as well XGBE network processors.

Jarkko Sakkinen 313d21eeab tpm: device class for tpm
Added own device class for TPM. Uses MISC_MAJOR:TPM_MINOR for the
first character device in order to retain backwards compatibility.
Added tpm_dev_release() back attached to the character device.

I've been running this code now for a while on my laptop (Lenovo
T430S) TrouSerS works perfectly without modifications. I don't
believe it breaks anything significantly.

The sysfs attributes that have been placed under the wrong place
and are against sysfs-rules.txt should be probably left to
stagnate under platform device directory and start defining
new sysfs attributes to the char device directory.

Guidelines for future TPM sysfs attributes should be probably
along the lines of

- Single flat set of mandatory sysfs attributes. For example,
  current PPI interface is way way too rich when you only want
  to use it to clear and activate the TPM.

- Define sysfs attribute if and only if there's no way to get
  the value from ring-3. No attributes for TPM properties. It's
  just unnecessary maintenance hurdle that we don't want.

Paul E. McKenney 5cd37193ce rcu: Make cond_resched_rcu_qs() apply to normal RCU flavors
Although cond_resched_rcu_qs() only applies to TASKS_RCU, it is used
in places where it would be useful for it to apply to the normal RCU
flavors, rcu_preempt, rcu_sched, and rcu_bh.  This is especially the
case for workloads that aggressively overload the system, particularly
those that generate large numbers of RCU updates on systems running
NO_HZ_FULL CPUs.  This commit therefore communicates quiescent states
from cond_resched_rcu_qs() to the normal RCU flavors.

Note that it is unfortunately necessary to leave the old ->passed_quiesce
mechanism in place to allow quiescent states that apply to only one
flavor to be recorded.  (Yes, we could decrement ->rcu_qs_ctr_snap in
that case, but that is not so good for debugging of RCU internals.)
In addition, if one of the RCU flavor's grace period has stalled, this
will invoke rcu_momentary_dyntick_idle(), resulting in a heavy-weight
quiescent state visible from other CPUs.
