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

Pull ARM SoC updates for Marvell mvebu/kirkwood from Olof Johansson:
 "This is a branch with updates for Marvell's mvebu/kirkwood platforms.
  They came in late-ish, and were heavily interdependent such that it
  didn't make sense to split them up across the cross-platform topic
  branches.  So here they are (for the second release in a row) in a
  branch on their own."
