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.
