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

Pull ARM SoC non-critical fixes from Olof Johansson:
 "Here's a small collection of fixes accrued during the last release
  that weren't considered severe enough to merge during the -rc series.

  A few of these are around resurrecting TI81xx support that's been
  broken for quite a while, the rest are smaller fixes -- most for PXA
  but a few across the board.

  There are also some updates to MAINTAINERS here, in particular for
  Broadcom platforms"
