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

Pull ARM SoC fixes from Olof Johansson:
 "This is a largeish batch of fixes, mostly because I missed -rc2 due to
  travel/vacation.  So in number these are a bit more than ideal unless
  you amortize them over two -rcs.

  Quick breakdown:
   - Defconfig updates
     - Making multi_v7_defconfig useful on more hardware to encourage
       single-image usage
     - Davinci and nomadik updates due to new code merged this merge
       window
   - Fixes for UART on Samsung platforms, both PM and clock-related
   - A handful of warning fixes from defconfig builds, including for
     max8925 backlight and pxamci (both with appropriate acks)
   - Exynos5440 fixes for LPAE configuration, PM
   - ...plus a bunch of other smaller changes all over the place

  I expect to switch to regressions-or-severe-bugs-only fixes from here
  on out"
