Merge tag 'iio-for-4.12a' of git://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio into staging-next
Jonathan writes:
First set of IIO new device support, features and cleanup for the 4.12 cycle.
Quite a bit of outreachy activity here with a driver from a current intern
and a number of cleanup patches as part of the next round.
Getting a pull request in early this cycle as it's looking like another large
cycle for IIO.
New device support
* adxl345
- initial device support. Note, once complete support is done the intent
is to superceded the driver in input/misc.
- bindings.
- conversion from i2c direct calls to regmap and driver split.
- spi support.
* chromeos light and proximity.
- new driver.
* devantech srf04 ultrasonic ranger
- new driver with device tree bindings.
* hid temperature
- new driver for environemntal temperature support from hid devices.
* max30102 oximeter
- new driver with device tree bindings.
* st lsm6dsx
- refactor and addition of device support for lsm6dsl and lsm6ds3h.
Staging graduation
* isl29028 including copyright notice update to reflect Brian's work.
* lpc32xx_adc.
* spear adc. It's not perfect and there are some datasheet disagreements, but
it works and is good enough to graduate.
New features
* documentation
- abi docs for in_proximity_sampling_frequency_available.
- generalise counting direction ABI docs as a second driver is going to
use them.
* hid-sensor-prox
- Add support for HID_USAGE_SENSOR_HUMAN_PRESENCE if used on a particular
device.
* isl29028
- runtime pm.
* meson-saradc
- switch from polling to interrupt mode and improved read_raw_sample function
to avoid unnecessary loop.
* tmp007
- interrupt and threshold event support.
Cleanups and minor fixes
* ad2s1210
- permissions to octal.
* ad7192
- permissions to octal.
- use BIT macro.
* ad9832
- merge header definitions into source file.
* ad9834
- merge header definitions into source file.
* ade7753
- merge header definitions into source file.
- cleanup include ordering.
* ade7854
- simplify return logic.
* adis16201
- merge header definitions into source file.
- rename _core.c to .c as there is nothing else.
* adis16203
- merge header definitions into source file.
- rename _core.c to .c as there is nothing else.
* adis16209
- merge header definitions into source file.
- rename _core.c to .c as there is nothing else.
* adis16240
- permissions to octal.
- merge header definitions into source file.
- rename _core.c to .c as there is nothing else.
* adt7136
- permissions to octal.
* cio-dac
- set missing parent device.
* documentation
- update version numbers on sysfs ABI for counter bits that didn't quite.
make 4.9.
* isl29028
- mdelay to msleep.
- incorrrect sleep time when taking first proximity reading.
* lmp91000
- set missing parent device.
* lpc32xx
- Consistent prefixes for defines.
- rename local state structure to _state.
* max30100
- set missing parent device.
* max30102
- set missing parent device.
* maxim-thermocouple
- set missing parent device.
* meter driver header
- permissions to octal.
* pulsedlight-lidar-lite-v2
- set missing parent device.
* quad-8
- set missing parent device.
* st104
- set missing parent device.
Other
* Mailmap
- update Matt Ranostay's email address to the Konsolko one.
