Jonathan writes:

3rd round of IIO new drivers, cleanups and functionality for the 3.17 cycle.

New drivers
* isl29125 digital color light sensor driver
* TAOS/AMS tcs3414 digital color sensor

Staging graduation
* ad7291 ADC driver.

New functionality
* st_sensors - device tree support and bindings
* mma8452 - device tree support

Cleanups
* Drop redundant variables in a number of drivers.
* Reorder a structure definition to ealy wiht a warning about static
  not being at the beginning in the hid-sensors driver.
* Switch a few more drivers away from using explicit sampling_frequency
  attribute to providing this through the core.
* Make hid_sensor_get_reporting_interval static as only used within a single
  file.
* Drop a redundant check for negative values in an unsigned variable from
  ad9832
* Drop some duplicate case labels in the event monitor example code.
* Use devm_ioremap_resource to simplify error handling.
* Use devm_kzalloc within the blackfin timer driver to simplify error
  handling and removal.
* A number of cleanups of the ad7291 from Hartmut Knaack in response
  to a patch moving it out of staging.
* Core support for the period info element about events.  It has been
  in the abi for a while, but not added until now to the newer handling
  of information related to events.
* Add HAS_IOMEM dependency to mxs_lradc to avoid build issues when testing
  enabled.

STMicroelectronics MEMS sensors
The STMicroelectronics sensor devices are pretty straight-forward I2C or
SPI devices, all sharing the same device tree descriptions no matter what
type of sensor it is.
Required properties:
- compatible: see the list of valid compatible strings below
- reg: the I2C or SPI address the device will respond to
Optional properties:
- vdd-supply: an optional regulator that needs to be on to provide VDD
power to the sensor.
- vddio-supply: an optional regulator that needs to be on to provide the
VDD IO power to the sensor.
- st,drdy-int-pin: the pin on the package that will be used to signal
"data ready" (valid values: 1 or 2). This property is not configurable
on all sensors.
Sensors may also have applicable pin control settings, those use the
standard bindings from pinctrl/pinctrl-bindings.txt.
Valid compatible strings:
Accelerometers:
- st,lsm303dlh-accel
- st,lsm303dlhc-accel
- st,lis3dh-accel
- st,lsm330d-accel
- st,lsm330dl-accel
- st,lsm330dlc-accel
- st,lis331dlh-accel
- st,lsm303dl-accel
- st,lsm303dlm-accel
- st,lsm330-accel
Gyroscopes:
- st,l3g4200d-gyro
- st,lsm330d-gyro
- st,lsm330dl-gyro
- st,lsm330dlc-gyro
- st,l3gd20-gyro
- st,l3g4is-gyro
- st,lsm330-gyro
Magnetometers:
- st,lsm303dlhc-magn
- st,lsm303dlm-magn
- st,lis3mdl-magn
Pressure sensors:
- st,lps001wp-press
- st,lps25h-press
- st,lps331ap-press
