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:
 "This week's arm-soc fixes:

   - A set of of OMAP patches that we had missed Tony's pull request of:
     * Reset fix for am43xx
     * Proper OPP table for omap5
     * Fix for SoC detection of one of the DRA7 SoCs
     * hwmod updates to get SATA and OCP to work on omap5 (drivers
       merged in 3.16)
     * ... plus a handful of smaller fixes
   - sunxi needed to re-add machine specific restart code that was
     removed in anticipation of a watchdog driver being merged for 3.16,
     and it didn't make it in.
   - Marvell fixes for PCIe on SMP and a big-endian fix.
   - A trivial defconfig update to make my capri test board boot with
     bcm_defconfig again.

  ... and a couple of MAINTAINERS updates, one to claim new Keystone
  drivers that have been merged, and one to merge MXS and i.MX (both
  Freescale platforms).

  The largest diffs come from the hwmod code for omap5 and the re-add of
  the restart code on sunxi.  The hwmod stuff is quite late at this
  point but it slipped through cracks repeatedly while coming up the
  maintainer chain and only affects the one SoC so risk is low"
