Jonathan writes:

Second set of iio new device support, features and cleanups for the 4.9 cycle.

New device support
* ad8801 dac
  - new driver supporting ad8801 and ad8803 DACs.
* adc12138
  - new driver supporting TI adc12130/adc12132 and adc12138 ADCs.
* ltc2485 adc
  - new driver
* mxc6255
  - add support for the mxc6225 part name and fixup the ID check so it works.
* vz89x VOC sensor
  - add support for the vz89te part which drops the voc_short channel and adds
    CRCs compared to other supported parts.

New features
* core
  - immutable triggers.  These effectively grant exclusive control over a
    trigger. The typical usecase is a device representing an analog part
    (perhaps a MUX) that needs to control the sampling of a downstream
    ADC.
  - resource managed trigger registration and triggered_buffer_init.
  - iio_push_event now protected against case of the event interface
    registration not having yet occured.  Only matters if an interrupt
    can occur during this window - might happen on shared interrupt lines.
  - helper to let a driver query if the trigger it is using is provided by
    itself (using the convention of both device and trigger having the same
    parent).
* tools
  - iio-utils. Used channel modifier scaling in preference to generic scaling
    when both exist.
* at91-adc
  - Add support for touchscreen switches closure time needed by some newer
    parts.
* stx104
  - support the ADC channels on this ADC/DAC board. As these are the primary
    feature of the board also move the driver to the iio/adc directory.
* sx9500
  - device tree bindings.

Cleanups / Fixes
* ad5755
  - fix an off-by-one on devnr limit check (introduced earlier this cycle)
* ad7266
  - drop NULL check on devm_regulator_get_optional as it can't return NULL.
* ak8974
  - avoid an unused functional warning due to rework in PM core code.
  - remove .owner field setting as done by i2c_core.
* ina2xx
  - clear out a left over debug field from chip global data.
* hid-sensors
  - avoid an unused functional warning due to rework in PM core code.
* maxim-thermocouple
  - fix non static symbol warnings.
* ms5611
  - fetch and enable regulators unconditionally when they aren't optional.
* sca3000
  - whitespace cleanup.
* st_sensors
  - fetch and enable regulators unconditionally rather than having them
    supported as optional regulators (missunderstanding on my part amongst
    others a while back)
  - followup to previous patch fixes error checking on the regulators.
  - mark symbols static where possible.
  - use the 'is it my trigger' help function.  This prevents the odd case
    of another device triggering from the st-sensors trigger whilst the
    st-sensors trigger is itself not using it but rather using say an hrtimer.
* ti-ads1015
  - add missing of_node_put.
* vz89x
  - rework to all support of new devices.
  - prevent reading of a corrupted buffer.
  - fixup a return value of 0/1 in a bool returning function.

Address updates
- Vlad Dogaru email address change.

Jonathan writes:

First round of new features, device support and cleanups for IIO in the 4.9 cycle.

Device support

* ak8974
  - New driver and bindings for this 2009 vintage magnetometer (it was very
    popular back then!)
* atlas-ph-sensor
  -  ORP sensor support(I had to look up what one of these was)
* cio-dac
  - New driver for Measurement Computing DAC boards
* dmard06
  - New driver for Domintech DMARDO6 accelerometer. Also vendor prefix.
* dmard09
  - New driver for Domintech DMARD09 accelerometer.
* maxim-thermocouple
  - max6675 and max31855 new driver
* mt6577 auxdac
  - new driver for this Mediatek chip mt2701, mt6577 and mt8173 have this
    hardware.
* ti-adc161s626
  - new driver for this TI single channel differential ADC.
* vcnl4000
  - support vcnl4010 and vcnl4020 which are compatible for all features
    currently supported by this driver.

New features

* Core
  - Allow retrieving of underlying iio_dev from a callback buffer handle.
    This is needed to allow client drivers to perform operations such as
    configuring the trigger used.
* hid-sensors
  - asynchronous resume support to avoid really long resume times.
* kxcjk-1013
  - add the mysterious KIOX000A ACPI id seen in the wild.
* Tools
  - lsiio now enumerates processed as well as raw channels.

Cleanup

* ad7298
  - use iio_device_claim_direct_mode and friends to simplify locking around
    mode switching and drop some boilerplate.
* ad7793
  - use iio_device_claim_direct_mode and friends to simplify locking around
    mode switching and drop some boilerplate.
* ade7854
  - checkpatch fixups (alignment of parameters)
* atlas-ph-sensor
  - use iio_device_claim_direct_mode and friends to simplify locking around
    mode switching and drop some boilerplate.
  - Switch to REGCACHE_NONE as there are no useful register to cache.
* bma180
  - use iio_device_claim_direct_mode and friends to simplify locking around
    mode switching and drop some boilerplate.
* hdc100x
  - Add mention of the HDC1000 and HDC1008 to the Kconfig help text.
* isl29018
  - Add driver specific prefixes to defines and function names.
  - Remove excessive logging.
  - Drop newlines which add nothing to readability.
  - General tidying up of comments.
  - Drop I2C_CLASS_HWMON as irrelevant to driver.
* isl29028
  - Add driver specific prefixes to defines, enums and function names.
  - Drop comma's from available attribute output as not ABI compliant.
  - Drop I2C_CLASS_HWMON as irrelevant to driver.
* kxsd9
  - devicetree bindings.
* mag3110
  - This one wasn't locking to protect against mode switches during
    raw_reads.  Use the iio_claim_direct_mode function to fix this buglet.
* maxim-theromcouple
  - Fix missing selects for triggered buffer support in Kconfig.
* nau7802
  - Use complete instead of complete_all as only one completion at a time.
* sx9500
  - Use complete instead of complete_all as only one completion at a time.
* us5182d
  - Add a missing error code asignment instead of checking the result of
    an already checked statement.
* vcnl4000
  - Use BIT macro where appropriate.
  - Refactor return codes in read_raw callback.
  - Add some missing locking for concurrent accesses to the device.

 "Device tree contents continue to be the largest branches we submit.
  This time around, some of the contents worth pointing out is:

  New SoC platforms:
   - Freescale i.MX 7Solo
   - Broadcom BCM23550
   - Cirrus Logic EP7209 and EP7211 (clps711x platforms)_
   - Hisilicon HI3519
   - Renesas R8A7792

  Some of the other delta that is sticking out, line-count wise:
   - Exynos moves of IP blocks under an SoC bus, which causes a large
     delta due to indentation changes
   - a new Tegra K1 board: Apalis
   - a bunch of small updates to many Allwinner platforms; new hardware
     support, some cleanup, etc"

97eacb9166 iio:ak8975: add mounting matrix support
Expose a rotation matrix to indicate userspace the chip orientation with
respect to the overall hardware system.
Matrix is retrieved from "in_mount_matrix". It is declared into ak8975 DTS
entry as a "mount-matrix" property.

0e6f6871a1 iio: st_sensors: support open drain mode
Some types of ST Sensors can be connected to the same IRQ line
as other peripherals using open drain. Add a device tree binding
and a sensor data property to flip the right bit in the interrupt
control register to enable open drain mode on the INT line.

If the line is set to be open drain, also tag on IRQF_SHARED
to the IRQ flags when requesting the interrupt, as the whole
point of using open drain interrupt lines is to share them with
more than one peripheral (wire-or).

Jonathan writes:

First round of IIO new device support, features and cleanups for the 4.7 cycle.

New core support
* UV light modifier (for intensity)
* UV light index channel type.

New device support
* hp206c barometer and altimeter
  - new driver.
* mcp4131 potentiometer
  - new driver supporting lots of parts from Microchip.
* mma8452
  - FXLS8471Q support
- NXP LPC18XX SOC ADC
  - new driver.
- NXP LPC18XX SOC DAC
  - new driver.
- rockchip_saradc
  - support rk3399
* st accel
  - h3lis331dl support

Staging driver removals
* adis16204
  - obsolete part making it hard to get parts to test the driver in order
    to clean it up.
* adis16220
  - obsolete part making it hard to get the parts test the driver in order
    to clean it up.

Features
* core
  - convenience functions to claim / release direct access to the device.
    Makes more consistent handling of this corner easier. Used in ad7192 driver.
* ak8975
  - power regulator support.
* at91-sama5d2
  - differential channel support.
* mma8452
  - runtime pm support
  - drop device specific autosleep and use the runtime pm one instead.
* ms5611
  - DT bindings
  - oversampling ratio support

Cleanups and minor fixes
* MAINTAINERS
  - Peter got married - hence name change!

* Documentation
  - Fix a typo in in_proximity_raw description.
  - Add some missing docs for iio_buffer_access_funcs.

* Tools
  - update iio_event_monitor names to match new stuff.
  - make generic_buffer look for triggers ending in -trigger as we let these in
  for a number of drivers a long time back and now it is a fairly common
  option.

Drivers
* staging wide
  - convert bare unsigned usage to unsigned int to comply with coding style.
* non staging wide:
  - since boiler plate gpio handling of interrupts has been moved into the
   ACPI core we don't need to include gpio/consumer.h in a load of drivers so
   drop it.
* ad7606
  - fix an endian casting sparse warning.
* ak8975
  - fix a possible unitialized warning from gcc.
  - drop and unused field left over from earlier cleanups
  - fix a missing regulator_disable on exit.
* at91-sama5d2
  - typo and indentation
  - missing IOMEM dependency.
  - cleanup mode register usage by avoidling erasing whole thing when changing
  the sampling frequency.
* bmc150
  - use the core demux and available_scan_masks to simplify buffer handling
  - optimize the transfers in the trigger handler now we have a magic function
  to emulate bulk reads (under circumstances met here).  This matters with some
  rather dumb i2c adapters in particular.
  - use a single regmap_conf for all bus types as they were all the same.
* bmg160
  - use the core demux and available_scan_masks to simplify the buffer handling
  - optimize the transfers in the trigger handler now we have a magic funciton
  to emulate bulk rads (under circumstances met here).
  - drop gpio interrupt probing from the driver (ACPI) as now handled by the
  ACPI core.
* ina2xx-adc
  - update the CALIB register when RShunt changes.
  - fix scale for VShunt - in reality this error canceled out when used.
* isl29028
  - use regmap to retrieve the struct device instead of carrying a second
  copy of it around.
* kxcjk-1013
  - use core demux
  - optimize i2c transfers in the trigger handler.
* mcp4531
  - refactor to use a pointer to access model parameters instead of indexing
    into the array each time.
* mma8452
  - style fixes
  - avoid swtiching to active whenever the config changes
  - add missin i2c_device_id for mma8451
* mpu6050
  - fix possible NULL dereference.
  - fix the name / chip_id used when ACPI used (otherwise reports as NULL).
* ms5611
  - fix a missing regulator_disable that left the regulator on during removal.
* mxc4005
  - drop gpio interrupt handling for ACPI case from driver as the core now
  handles this case.
* st-sensors
  - note that there are only ever a maximum of 3 axis on current st-sensors
  so just allocate a fixed sized buffer big enough for that.
* tpl0102
  - change the i2c_check_functionality condition to bring it inline with other
    IIO users as EOPNOTSUPP.
* tsl2563
  - replace deprecated flush_scheduled_work

We use MMA8451Q's configuration because for what the driver supports,
FXLS8471Q is the same.

Support for FXLS8471Q's features (fast SPI interface and a larger FIFO,
among others) can be added to this driver anytime.
