Merge tag 'dt2' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc

Pull ARM soc device tree updates, take 2 from Olof Johansson:
 "This branch contains mostly a set of changes for device tree bindings
  on Samsung Exynos.  It was staged behind the other branches due to
  dependencies on pincontrol and board changes."

Fix up trivial conflict in drivers/clocksource/Makefile due to earlier
conflict resolution.

* tag 'dt2' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc:
  ARM: dts: Add nodes for dw_mmc controllers for Samsung EXYNOS5250 platforms
  ARM: EXYNOS: Add AUXDATA support for MSHC controllers
  ARM: EXYNOS: Add support for MSHC controller clocks
  ARM: dts: Enable on-board keys as wakeup source for exynos4210-origen
  ARM: dts: use uart2 for console on smdkv310 and smdk5250
  ARM: dts: Add basic dts file for Samsung Trats board
  ARM: EXYNOS: Add OF compatibility lookups for EXYNOS4 i2c adapters
  ARM: dts: Specify address and size cells for i2c controllers for EXYNOS4
  ARM: dts: Assume status of all optional nodes as disabled for exynos4
  ARM: EXYNOS: Use exynos4 prefix instead of exynos4210 on exynos4-dt
  ARM: dts: Move parts common to EXYNOS4 from exynos4210.dtsi to exynos4.dtsi
