Irina Tirdea d5b97f5c7d iio: accel: mma9551: split driver to expose mma955x api
Freescale has the MMA955xL family of devices that use the
same communication protocol (based on i2c messages):
http://www.freescale.com/files/sensors/doc/data_sheet/MMA955xL.pdf.

To support more devices from this family, we need to split the
mma9551 driver so we can export the common functions that will
be used by other mma955x drivers.

Irina Tirdea 6da93a6710 iio: accel: mma9551: Add runtime pm support
Add support for runtime pm to reduce the power consumed by the device
when not used.

If CONFIG_PM is not enabled, the device will be powered on at
init and only powered off on system suspend.

If CONFIG_PM is enabled, runtime pm autosuspend is used:
- for raw reads will keep the device on for a specified time
- for events it will keep the device on as long as we have at least
one event active

Irina Tirdea 17a2cbc279 iio: core: Remove IIO_EV_TYPE_INSTANCE
By introducing IIO_EV_TYPE_CHANGE, IIO_EV_TYPE_INSTANCE becomes redundant.
The effect of IIO_EV_TYPE_INSTANCE can be obtained by using IIO_EV_TYPE_CHANGE
with IIO_EV_INFO_VALUE set to 1.

Remove all instances of IIO_EV_TYPE_INSTANCE and replace them with
IIO_EV_TYPE_CHANGE where needed.

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.

Merge tag 'iio-for-3.20a_take2' of git://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio into staging-testing

Jonathan writes:

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.

Daniel Baluta df1fad80df iio kmx61 / PM: Replace CONFIG_PM_RUNTIME with CONFIG_PM
After commit b2b49ccbdd (PM: Kconfig: Set PM_RUNTIME if PM_SLEEP is
selected) PM_RUNTIME is always set if PM is set, so #ifdef blocks
depending on CONFIG_PM_RUNTIME may now be changed to depend on
CONFIG_PM.

Replace CONFIG_PM_RUNTIME with CONFIG_PM everywhere under

Linus Torvalds d0ac5d8e67 ARM: SoC fixes
We've been sitting on our fixes branch for a while, so this batch is
 unfortunately on the large side.
 
 A lot of these are tweaks and fixes to device trees, fixing various bugs
 around clocks, reg ranges, etc. There's also a few defconfig updates
 (which are on the late side, no more of those).
 
 All in all the diffstat is bigger than ideal at this time, but the nothing
 in here seems particularly risky.
