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

Pull ARM SoC platform updates from Olof Johansson:
 "Most of these are for MMP (seeing a bunch of cleanups and refactorings
  for the first time in a while), and for OMAP (a bunch of cleanups and
  added support for voltage controller on OMAP4430)"
