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

Pull ARM SoC fixes from Olof Johansson:
 "Seems like we've had more fixes than usual this release cycle, but
  there's nothing in particular that we're doing differently.  Perhaps
  it's just one of those cycles where more people are finding more
  regressions (and/or that the latency of when people actually test
  what's been in the tree for a while is catching up so that we get the
  bug reports now).

  The bigger changes here are are for TI and Marvell platforms:
   * Timing changes for GPMC (generic localbus) on OMAP causing some
     largeish DTS deltas.
   * Fixes to window allocation on PCI for mvebu touching drivers/
     stuff.  Patches have acks from subsystem maintainers where needed.
   * A fix from Thomas for a botched DT conversion in drivers/edma.

  There's a handful of other fixes for the above platforms as well as
  sunxi, at91, i.MX.  I also included a MAINTAINER update for Broadcom,
  and a trivial move of a binding doc.

  I know you said you'd be offline this week, but I might as well post
  it for when you return.  :)"

I'm not quite offline yet.  Doing a few pulls in the last hour before my
internet goes away..
