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

Pull ARM SoC fixes from Olof Johansson:
 "Things are calming down nicely here w.r.t. fixes.  This batch
  includes two week's worth since I missed to send before -rc4.

  Nothing particularly scary to point out, smaller fixes here and there.
  Shortlog describes it pretty well"
