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

Pull ARM SoC late fixes and dependencies 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.

  Other than the fixes, the primary feature being added is the
  conversion of some OMAP drivers to the new generic wakeirq interface"
