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

Pull ARM SoC fixes from Olof Johansson:
 "People are back from the holiday breaks, and it shows.  Here are a
  bunch of fixes for a number of platforms:
   - A couple of small fixes for Nomadik
   - A larger set of changes for kirkwood/mvebu
     - uart driver selection, dt clocks, gpio-poweroff fixups, a few
       __init annotation fixes and some error handling improvement in
       their xor dma driver.
   - i.MX had a couple of minor fixes (and a critical one for flexcan2
     clock setup)
   - MXS has a small board fix and a framebuffer bugfix
   - A set of fixes for Samsung Exynos, fixing default bootargs and some
     Exynos5440 clock issues
   - A set of OMAP changes including PM fixes and a few sparse warning
     fixups

  All in all a bit more positive code delta than we'd ideally want to
  see here, mostly from the OMAP PM changes, but nothing overly crazy."
