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

Pull ARM SoC fixes from Kevin Hilman:
 "About 10 days worth of small bug fixes, and the (hopefully) final
  round fixes for from arm-soc land for the -rc cycle.  Nothing special
  to note, but here's a brief summary of fixes by SoC type:

   - OMAP:
        small set of misc DT fixes; boot fix for THUMB2 kernel

   - mediatek:
        PMIC fixes; DT fix for model name

   - exynos:
        wakeup interupt fixes for 3250

   - mvebu:
        revert mbus patch which broke DMA masters
