   ARM: dts: Fix wrong compatible string for Exynos3250 ADC (2014-07-23 21:59:03 +0100)

----------------------------------------------------------------
Fourth round of IIO new drivers, functionality and cleanups for the 3.17 cycle

New functionality
* A new modifier to indicate that a rotation is relative to either
   true or magnetic north.  This is to be used by some magnetometers
   that provide data in this way.
* hid magnetometer now supports output rotations from various variants on
   North
* HMC5843 driver converted to regmap and reworked to allow easy support
   of other similar devices.  Support for HMC5983 added via both i2c and SPI.
* Rework of Exynos driver to simplify extension to support more devices.
* Addition of support for the Exynos3250 ADC (which requires an additional
   clock)  Support for quite a few more devices on its way.

Cleanups
* ad7997 - a number of cleanups and tweaks to how the events are controlled
   to make it more intuitive.
* kxcjk - cleanups and minor fixes for this new driver.
