Merge tag 'iio-for-3.16a' of git://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio into staging-next

Jonathan writes:

First round of IIO new driver, functionality and cleanups for the 3.16 cycle.

New device support
* AS3935 Lightning Sensor
* MCP3426/7/8 support added to the existing MCP3422 ADC driver
* AK8963 support in the AK8975 driver
* MPU6500 support in the MPU6050 driver (the functionality that is different
  is mostly not supported yet in either part).

Staging Graduations
* AD799x ADC

New functionality
* ACPI enumeration for the ak8975 driver

Cleanup / tweaks
* Use snprintf as a matter of good practice in a few additional places.
* Document *_mean_raw attributes.  These have been there a while, but were
  undocumented.
* Add an in kernel interface to get the mean values.
* Bug in the length of the event info mask that by coincidence wasn't yet
  actually causing any problems.
* itg3000 drop an unreachable return statement.
* spear_adc cleanups (heading for a staging graduation but a few more
  issues showed up in the review of these patches).
* Exynos ADC dependencies changed so it is only built when Exynos is present
  or COMPILE_TEST and OF are set.
* tsl2583 cleanups.
* Some cut and paste typos in the comments of various drivers still in staging.
* Couple of minor improvements to the ST sensor drivers.

Austrian Microsystems AS3935 Franklin lightning sensor device driver



Required properties:

	- compatible: must be "ams,as3935"

	- reg: SPI chip select number for the device

	- spi-cpha: SPI Mode 1. Refer to spi/spi-bus.txt for generic SPI

	slave node bindings.

	- interrupt-parent : should be the phandle for the interrupt controller

	- interrupts : the sole interrupt generated by the device



	Refer to interrupt-controller/interrupts.txt for generic

	interrupt client node bindings.



Optional properties:

	- ams,tuning-capacitor-pf: Calibration tuning capacitor stepping

	  value 0 - 120pF. This will require using the calibration data from

	  the manufacturer.



Example:



as3935@0 {

	compatible = "ams,as3935";

	reg = <0>;

	spi-cpha;

	interrupt-parent = <&gpio1>;

	interrupts = <16 1>;

	ams,tuning-capacitor-pf = <80>;

};
