Irina Tirdea 40cb761306 iio: add driver for Freescale MMA9553
Add support for Freescale MMA9553L Intelligent Pedometer Platform.

The following functionalities are supported:
 - step counter (counts the number of steps using a HW register)
 - step detector (generates an iio event at every step the user takes)
 - activity recognition (rest, walking, jogging, running)
 - speed
 - calories
 - distance

To get accurate pedometer results, the user's height, weight and gender
need to be configured.

The specifications can be downloaded from:

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.

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.
 
 Misc
  * Add IIO include files to the maintainers entry.

   wrong parameters as a result of the above rework.

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

 * Small cleanups in adf4530 driver - pointless message and unnecessary braces.
 * Clarifiy the proximity ABI docs to make it clear it should get bigger

 * Drop a misleading comment form industrialio-core.c
 * Trivial white space cleanups.
 * sca3000 looses an unused debug function.

 * A couple of cleanups for the staging ad5933 driver to avoid unnecessary

Laszlo Ersek 957c811147 devicetree: document the "qemu" and "virtio" vendor prefixes
The QEMU open source machine emulator and virtualizer presents firmware
and operating systems running in virtual machines ("guests") with purely
virtual hardware (ie. hardware that has never existed in physical form).
Since QEMU exposes some of these devices in a DTB, it makes sense to
define "qemu" and "virtio" as vendor prefixes.

The qemu definition is from [1], revision 4451 (22:24, 25 November 2014).

The virtio definition is composed from [2] and [3].

Laszlo Ersek 53275a61bc devicetree: document ARM bindings for QEMU's Firmware Config interface
Peter Maydell suggested that we describe new devices / DTB nodes in the
kernel Documentation tree that we expose to arm "virt" guests in QEMU.

Although the kernel is not required to access the fw_cfg interface,
"Documentation/devicetree/bindings/arm" is probably the best central spot
to keep the fw_cfg description in.

Kuninori Morimoto 7c7a9b3de5 of: replace Asahi Kasei Corp vendor prefix
Current vendor-prefixes.txt already has "ak" prefix for Asahi Kasei Corp
by ae8c4209af2c(of: Add vendor prefix for Asahi Kasei Corp.)

It went through the appropriate review process. But, almost all
Asahi Kasei chip drivers are using "asahi-kasei" prefix today.
(arch/arm/boot/dts/tegra20-seaboard.dts only is using "ak,ak8975",
 but there are instances of "asahi-kasei,ak8975" in other dts files.
 And drivers/iio/magnetometer/ak8975.c doesn't support "ak,ak8975" prefix)
So, we made a mistake there.

In addition, checkpatch.pl reports WARNING if it is using "asahi-kasei"
prerfix in DT file.
(DT compatible string vendor "asahi-kasei" appears un-documented)

Marking it deprecated and warning with checkpatch is certainly
preferable. So, this patch replace "ak" to "asahi-kasei" in
vendor-prefixes.txt. (and fixup tegra20-seaboard)

OTOH, Asahi Kasei is usually referred to as "AKM", but this patch
doesn't care about it. Because no DT is using that today.

On some laptops, keyboard needs to be reset in order to successfully detect
touchpad (e.g., some Gigabyte laptop models with Elantech touchpads).
Without resettin keyboard touchpad pretends to be completely dead.

Based on the original patch by Mateusz Jończyk this version has been
expanded to include DMI based detection & application of the fix
automatically on the affected models of laptops. This has been confirmed to
fix problem by three users already on three different models of laptops.

This patch fixes off-by-one issues in the devicetree binding of

According to the i.MX23 and i.MX28 reference manuals [1][2] the range of
NUM_SAMPLES is 0..31, but property ave-ctrl is substracted by 1 before used.

Considering all limitations the range of DELAY is 1..2047, but also
property ave-delay is substracted by 1 before used.

The patch has been suggested by Hartmut Knaack and Kristina Martsenko.

Linus Torvalds 34b85e3574 powerpc updates for 3.19 batch 2
The highlight is the series that reworks the idle management on powernv, which
 allows us to use deeper idle states on those machines.
 
 There's the fix from Anton for the "BUG at kernel/smpboot.c:134!" problem.
 
 An i2c driver for powernv. This is acked by Wolfram Sang, and he asked that we
 take it through the powerpc tree.
 
 A fix for audit from rgb at Red Hat, acked by Paul Moore who is one of the audit
 maintainers.
 
 A patch from Ben to export the symbol map of our OPAL firmware as a sysfs file,
 so that tools can use it.
 
 Also some CXL fixes, a couple of powerpc perf fixes, a fix for smt-enabled, and
 the patch to add __force to get_user() so we can use bitwise types.

Linus Torvalds c0f486fde3 More ACPI and power management updates for 3.19-rc1
- Fix a regression in leds-gpio introduced by a recent commit that
    inadvertently changed the name of one of the properties used by
    the driver (Fabio Estevam).
 
  - Fix a regression in the ACPI backlight driver introduced by a
    recent fix that missed one special case that had to be taken
    into account (Aaron Lu).
 
  - Drop the level of some new kernel messages from the ACPI core
    introduced by a recent commit to KERN_DEBUG which they should
    have used from the start and drop some other unuseful KERN_ERR
    messages printed by ACPI (Rafael J Wysocki).
 
  - Revert an incorrect commit modifying the cpupower tool
    (Prarit Bhargava).
 
  - Fix two regressions introduced by recent commits in the OPP
    library and clean up some existing minor issues in that code
    (Viresh Kumar).
 
  - Continue to replace CONFIG_PM_RUNTIME with CONFIG_PM throughout
    the tree (or drop it where that can be done) in order to make
    it possible to eliminate CONFIG_PM_RUNTIME (Rafael J Wysocki,
    Ulf Hansson, Ludovic Desroches).  There will be one more
    "CONFIG_PM_RUNTIME removal" batch after this one, because some
    new uses of it have been introduced during the current merge
    window, but that should be sufficient to finally get rid of it.
 
  - Make the ACPI EC driver more robust against race conditions
    related to GPE handler installation failures (Lv Zheng).
 
  - Prevent the ACPI device PM core code from attempting to
    disable GPEs that it has not enabled which confuses ACPICA
    and makes it report errors unnecessarily (Rafael J Wysocki).
 
  - Add a "force" command line switch to the intel_pstate driver
    to make it possible to override the blacklisting of some
    systems in that driver if needed (Ethan Zhao).
 
  - Improve intel_pstate code documentation and add a MAINTAINERS
    entry for it (Kristen Carlson Accardi).
 
  - Make the ACPI fan driver create cooling device interfaces
    witn names that reflect the IDs of the ACPI device objects
    they are associated with, except for "generic" ACPI fans
    (PNP ID "PNP0C0B").  That's necessary for user space thermal
    management tools to be able to connect the fans with the
    parts of the system they are supposed to be cooling properly.

Linus Torvalds 66dcff86ba 3.19 changes for KVM:
- spring cleaning: removed support for IA64, and for hardware-assisted
 virtualization on the PPC970
 - ARM, PPC, s390 all had only small fixes
 
 For x86:
 - small performance improvements (though only on weird guests)
 - usual round of hardware-compliancy fixes from Nadav
 - APICv fixes
 - XSAVES support for hosts and guests.  XSAVES hosts were broken because
 the (non-KVM) XSAVES patches inadvertently changed the KVM userspace
 ABI whenever XSAVES was enabled; hence, this part is going to stable.
 Guest support is just a matter of exposing the feature and CPUID leaves
 support.
 
 Right now KVM is broken for PPC BookE in your tree (doesn't compile).
 I'll reply to the pull request with a patch, please apply it either
 before the pull request or in the merge commit, in order to preserve
 bisectability somewhat.
