Jonathan writes:

Second round of new IIO drivers, features and cleanups for the 3.18 cycle.

New drivers and part support
* Bosch bmg160 Gyroscope driver
* Dyna-Image al3320a ambient light sensor driver
* Bosh bmi055 gyroscope part driver (accelerometer part supported by bmc150)
* isl29018 - add support for isl29023 and isl29035
* kxcjk-1013 - add support for kxcj9-1008 and kxtj2-1009
* bmc150 - additional part support (BMI055 accelerometer part, BMA255,
  BMA222E, BMA250E and BMA280).  Different resolutions but otherwise similar
  parts.
* bma180 - add BMA250 (note different from the BMA250E support above despite
  the naming).  A lot of driver reworking lead up to this - described below.

New features
* kxcjk1013 - add threshold event support.
* rockchip - document DT bindings.
* isl29018 - ACPI support
* bma180 - enable use without IRQ

Cleanups
* Tree wide - drop owner field assignment if using the module_platform_driver
  helper as that assigns it anyway.
* kxcjk1013 - drop a redundant assignment of the current range and fix a
  a defined but not used warning.
* inv_mpu6050 - Remove an unnecessary cast form a void pointer.
* rockchip - drop and unused variable.
* at91_adc - make a local function static.
* st-sensors-core - correctly handle an error in setting in
  st_sensors_set_drdy_int_pin
* isl29018 - typo fix
* bmc150 - fix incorrect scale value for 16G range (Driver new this cycle)
* bmc150 - fix issues when CONFIG_PM_RUNTIME not set (Driver new this cycle)
* ad7606 - line length tidy up.
* bmg160 - set power state only if PM_RUNTIME is defined.
* ak8975 - fix some unnecessary casting between char * and const char *
* bma180 - prefix remaining bits and bobs with bma180_ and ensure consistent.
         - use a bool instead of an int for state (as its either on or off).
         - expose the temperature channel
         - statically allocate buffers to avoid need for update_scan_mode
           callback.
         - refactor to allow futher chip variants including support for part
           specific config and disable code + different resolutions.

Documentation/ABI/testing/sysfs-bus-iio-gyro-bmg160

+What:		/sys/bus/iio/devices/triggerX/name = "bmg160-any-motion-devX"
+KernelVersion:	3.17
+Contact:	linux-iio@vger.kernel.org
+Description:
+		The BMG160 gyro kernel module provides an additional trigger,
+		which sets driver in a mode, where data is pushed to the buffer
+		only when there is any motion.

Documentation/devicetree/bindings/iio/adc/rockchip-saradc.txt

+Rockchip Successive Approximation Register (SAR) A/D Converter bindings
+
+Required properties:
+- compatible: Should be "rockchip,saradc"
+- reg: physical base address of the controller and length of memory mapped
+       region.
+- interrupts: The interrupt number to the cpu. The interrupt specifier format
+              depends on the interrupt controller.
+- clocks: Must contain an entry for each entry in clock-names.
+- clock-names: Shall be "saradc" for the converter-clock, and "apb_pclk" for
+               the peripheral clock.
+- vref-supply: The regulator supply ADC reference voltage.
+- #io-channel-cells: Should be 1, see ../iio-bindings.txt
+
+Example:
+	saradc: saradc@2006c000 {
+		compatible = "rockchip,saradc";
+		reg = <0x2006c000 0x100>;
+		interrupts = <GIC_SPI 26 IRQ_TYPE_LEVEL_HIGH>;
+		clocks = <&cru SCLK_SARADC>, <&cru PCLK_SARADC>;
+		clock-names = "saradc", "apb_pclk";
+		#io-channel-cells = <1>;
+		vref-supply = <&vcc18>;
