ec94efcdad The usual mixed bag of fixes for IIO in the 4.1 cycle.
Second version of this pull request as a small fix to a fix turned
 up before Greg pulled it for a cc10001 patch near the top of the tree.
 
 One core fix
 
 * Set updated for a iio kfifo was incorrectly set to false during a failed
   update, resulting in atttempts to repeat the failed operation appearing
   to succeed.
 
 This time I've decided to list the driver fixes in alphabetical order rather
 than 'randomly'.
 
 * axp288_adc - a recent change added a check for valid info masks when
   reading channels from consumer drivers.
 * bmp280 - temperature compensation was failing to read the tfine value, hence
   causing a temperature of 0 to always be returned and incorrect presure
   measurements.
 * cc10001 - Fix channel number mapping when some channels are reserved for
   remote CPUs. Fix an issue with the use of the power-up/power-down register
   (basically wrong polarity). Fix an issue due to the missinterpretting the
   return value from regulator_get_voltage. Add a delay before the start bit
   as recommended for the hardware to avoid data corruption.
 * hid pressure - fix channel spec of modfiied, but no modifier (which makes no
   sense!)
 * hid proximity - fix channel spec of modified, but no modifier (which makes
   no sense!). Fix a memory leak in the probe function.
 * mcp320x - occasional incorrect readings on dma using spi busses due to
   cacheline corruption. Fixed by forcing ___cacheline_aligned for the buffers.
 * mma9551 - buffer overrun fix (miss specified maximum length of buffers)
 * mma9553 - endian fix on status message. Add an enable element for activity
   channel. Input checking for activity period to avoid rather unpredictable
   results.
 * spmi-vadc - fix an overflow in the output value normalization seen on some
   boards.
 * st-snesors - oops due to use of a mutex that is not yet initialized during
   probe.
 * xilinx adc - Some wrong register addresses, a wrong address for vccaux
   channel, incorrect scale on VREFP and incorrect sign on VREFN.

8de29a35dc Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/jikos/hid
Pull HID updates from Jiri Kosina:

 - quite a few firmware fixes for RMI driver by Andrew Duggan

 - huion and uclogic drivers have been substantially overlaping in
   functionality laterly.  This redundancy is fixed by hid-huion driver
   being merged into hid-uclogic; work done by Benjamin Tissoires and
   Nikolai Kondrashov

 - i2c-hid now supports ACPI GPIO interrupts; patch from Mika Westerberg

 - Some of the quirks, that got separated into individual drivers, have
   historically had EXPERT dependency.  As HID subsystem matured (as
   well as the individual drivers), this made less and less sense.  This
   dependency is now being removed by patch from Jean Delvare

 - Logitech lg4ff driver received a couple of improvements for mode
   switching, by Michal Malý

 - multitouch driver now supports clickpads, patches by Benjamin
   Tissoires and Seth Forshee

 - hid-sensor framework received a substantial update; namely support
   for Custom and Generic pages is being added; work done by Srinivas
   Pandruvada

 - wacom driver received substantial update; it now supports
   i2c-conntected devices (Mika Westerberg), Bamboo PADs are now
   properly supported (Benjamin Tissoires), much improved battery
   reporting (Jason Gerecke) and pen proximity cleanups (Ping Cheng)

 - small assorted fixes and device ID additions

* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/jikos/hid: (68 commits)
  HID: sensor: Update document for custom sensor
  HID: sensor: Custom and Generic sensor support

dc5f2c5f6a First set of new drivers, cleanups and functionality for IIO in the 4.1 cycle.
New drivers
 * CM3323 color sensor.
 * MS5611 pressure and temperature sensor.
 
 New functionality
 * mup6050 - create mux clients for devices described via ACPI. The reasoning
      and approach taken in this patch are complex.  Basically there is no
      otherway of finding out what is there than by some esoteric look ups in
      the ACPI data.
 * cm3232 - PM support
 * itg3200 - suspend/resume support
 * mcp320x - add more ADCs to the kconfig to reflect what the driver supports
      (this patch and the bindings got left behind when the support was added
       a while back).
 
 Docs / utils
 * ti-adc128s052 - DT bindings.
 * mcp3422 - DT bindings.
 * mcp320x - DT bindings
 * ABI docs for event threshold scale attributes, in_magn_offset, proximity
   scan_element and thresh falling/rising values for accelerometers.  All
   elements long in use that have slipped by being explicitly documented.
 * Tidy up the tools previously in drivers/staging/iio/Documentation and move
   them out to /tools/iio. Yet another move that should have happened long ago.
   This time Roberta Dobrescu did the leg work.  Thanks!
 
 Core Cleanups
 * Export userspace IIO headers.  We should have done the appropriate header
   splitting a long time ago. Thanks to Daniel for sorting this out.
 
 * Refactor the registring of attributes for buffers to move all non-custom
   ones to a vector allowing easier additions to the current set in the future.
 
 Driver Cleanups
 * gpiod related cleanups.  Make use of the additional parameter to specify
   	initial direciton to avoid extra code.
 * bmc150 - Various refactorings to reduce code repitition and prepare for
            hardware buffer support.  Some of these cleanups are good even
 	   without the new functionality.
 * kmx61 - direct use of index to an array avoiding a structure element which
           was always the index to an element in an array of that structure.
 * vf610 - avoid incorrect type for return from wait_for_completion_timeout.
 * gp2ap020a00f - use put_unaligned_le32 for slight code simplification.
 * ade7754 - improve error handling including suppressing some build warnings.
 * ade7759 - improve error handling including suppressing some build warnings.
 * hmc5843 - Long line and indentation fixes. Also some constifying of various
       constant data.
 * ade7854 - 80+ character line splitting.
 * ad2s1210 - fix wrong printf format string.
 * mxs-lradc - fix wrong printf format string.
 * ade7954-i2c - code alignment fixes and other trivial but worthwhile bits.
 * periodic rtc trigger - make the frequency type an unsigned int as it
   is always treated as such.
 * jsa1212 - constify struct regmap_config as it is constant.
 * ad7793 - typo in the MODULE_DESCRIPTION
 * mma9551 - check gpiod_to_irq errors.  Note that this doesn't actually cause
     any trouble but is worth tidying up as obviously incorrect.
 * mlx90614 - refactor the register symbols to make it clear which reads are to
     RAM not PROM.

 * ssp_common - build warning fix for PM functions when PM not in use.
 * ak8975 - the addition of a utility library for this driver (as part of

 * mcp3422 - scale table was transposed.
 * ad5686 - use _optional regulator get to avoid a dummy reg being allocate

* mxs-lradc - fix up some interaction issues between the touchscreen driver
              and iio driver.  Mostly about making sure that the adc driver
              only affects channels that are not being used for the
              touchscreen.
* ad2s1200 - sign extension fix for a result of c type promotion.
* adis16400 - sign extension fix for a result of c type promotion.
* mcp3422 - scale table was transposed.
* ad5686 - use _optional regulator get to avoid a dummy reg being allocate
           which would cause the driver to fail to initialize.
* gp2ap020a00f - select REGMAP_I2C
* si7020 - revert an incorrect cleanup up and then fix the issue that made
           that cleanup seem like a good idea.

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.

  * Add IIO include files to the maintainers entry.

Added an API to allow client drivers to turn ON and OFF sensors for
quick read. Added data_read as counting varaible instead of boolean,
so that sensor is powered off only when last user released it.

* Fix the platform data support for the at91 adc driver.
 * A couple of related follow up patches get the support working again
   for at91sam9260 and at91sam9g45 as the earlier patch results in a device
   name change.
 * A default timer value in the at91 adc driver was bonkers.  Make it sane.
 * Fix incorrect reporting of the integration time for the cm32181 light sensor
 * Fix a missing break in the ad2s1200 driver which would have give a false
   error return.
 * Make sure buffer scan mask queries from userspace return 0/1 rather than
   a fairly random value depending on their implementation of test_bit
 * Fix leak of the i2c client and a null pointer dereference in the cm36651
   driver.
 * Fix a build warning on avr32 for the mxs-lradc (not exactly a critical
   combination - but the issue was real).

d0a588a57c iio: cm36651: Fix i2c client leak and possible NULL pointer dereference
During probe the driver allocates dummy I2C devices (i2c_new_dummy())
but they aren't unregistered during driver remove or probe failure.

Additionally driver does not check the return value of i2c_new_dummy().
In case of error (i2c_new_device(): memory allocation failure or I2C
address cannot be used) this function returns NULL which is later
dereferenced by i2c_smbus_{read,write}_data() functions.

Fix issues by properly checking for i2c_new_dummy() return value and
unregistering I2C devices on driver remove or probe failure.

Integration time of cm32181 is guessed about milliseconds.
But cm32181_read_als_it function return IIO_VAL_INT.
So fixed to return IIO_VAL_INT_PLUS_MICRO.
Next, add .write_raw_get_fmt callback function for call iio_str_to_fixpoint.

cm36651 have integration time from 1 to 640 milliseconds.
But, print more then the thousand second. when call *_integration_time attribute.
Because read_integration_time function return IIO_VAL_INT.
read integration time function is changed return IIO_VAL_INT_PLUS_MICRO;
And then .write_raw_get_fmt callback function for parse a fixed-point number from a string.
Some description is revised milliseconds unit.

81e990bbde First set of IIO fixes for the 3.14 cycle.
Included is the patch previously set as the fourth round for 3.13 which was
 to late to be appropriate.
 
 * Another endian fix (ad799x adc) due to missuse of the IIO_ST macro (which
   is going away very shortly)
 * A reversed error check in ad5933 which will make the probe fail.
 * A buffer overflow in the example code in the documentation.
 * ad799x was freeing an irq that might or might not have been requested.
 * tsl2563 was checking the wrong element of chan_spec for modifiers. Thus some
   sysfs reads would give the wrong values.
 * A missing dependency on HAS_IOMEM in spear_adc and lpc32xx was causing some
   test build failures (on s390 and perhaps elsewhere).
 
 I also have a few fixes queued up for things that went in during the 3.14
 merge window which will follow as a separate pull request (to avoid rebasing
 my tree).
