Merge tag 'iio-for-4.6a' of git://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio into staging-next
Jonathan writes:
First round of new IIO device support, features and cleanups for the 4.6 cycle.
Device Support
* ad5761
- new driver
* at91_sama5d2 ADC.
- new driver and MAINTAINERS entry.
- minor cleanups followed.
* atlas pH-SM
- new driver (this has possibly the prettiest data sheet I've ever seen)
* mcp3422
- mcp3425 ADC added.
* mcp4725
- mcp4726 DAC added.
* mma8452
- mma8451q accelerometer added.
* mpl115
- mpl115a1 added (a lot bigger than it seems as this is an SPI part whereas
previous parts were i2c).
* si7005
- Hoperf th02 (seems to be a repackaged part)
* si7020
- Hoperf th06 (seems to be a repackaged part)
New features
* Core
- IIO_PH type. Does what it says on the tin.
* max30100
- LED current configuration support.
* mcp320x
- more differential measurement combinations.
* mma8452
- free fall deteciton
- opt3001
- enable operation without a IRQ line.
- device tree docs. Somehow the original docs have disappeared down
a rabbit hole, so here is a new set.
* st-sensors
- Support active-low interrupts.
Cleanups and minor / not so minor reworks
* Documentation
- drop some defunct ABI from the docs in staging.
* presure / Kconfig
- white space cleanup.
* ad7150
- BIT macro usage
- Alignment fixes
* ad7192
- false indent fixed.
* ak8975
- constify the ak_def structures
* axp288
- drop a redundant double const.
* dht11
- substantial reliability improvements by being more tolerant
of missing start bits.
- simplify the decoding algorithm
* mma8452
- whitespace cleanup
* mpl115
- don't bother setting i2c_client_data as nothing uses it.
* mpu6050
- drop unused function parameter.
* opt3001
- extract integration time as constants.
- trivial refactoring.
