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

Pull late ARM SoC updates from Kevin Hilman:
 "This is a collection of a few late fixes and other misc stuff that had
  dependencies on things being merged from other trees.

  The bulk of the changes are for samsung/exynos SoCs for some changes
  that needed a few minor reworks so ended up a bit late.  The others
  are mainly for qcom SoCs: a couple fixes and some DTS updates"
