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

Pull ARM SoC fixes from Arnd Bergmann:
 "This is a rather unpleasantly large set of bug fixes for arm-soc, Most
  of them because of cross-tree dependencies for Exynos where we should
  have figured out the right path to merge things before the merge
  window, and then the maintainer being unable to sort things out in
  time during a business trip.

  The other changes contained here are the usual collection:

  MAINTAINERS file updates
   - Gregory Clement is now a co-maintainer for the legacy Marvell EBU
     platforms
   - A MAINTAINERS entry for the Freescale Vybrid platform that was
     added last year
   - Matt Porter no longer works as a maintainer on Broadcom SoCs

  Build-time issues
   - A compile-time error for at91
   - Several minor DT fixes on at91, imx, exynos, socfpga, and omap
   - The new digicolor platform was not correctly enabled at all

  Configuration issues
   - Two defconfig fix for regressions using USB on versatile express
     and on OMAP3
   - Enabling all 8 CPUs on Allwinner/SUNxi
   - Enabling the new STiH410 platform to be usable

  Bug fixes in platform code
   - A missing barrier for socfpga
   - Fixing LPDDR1 self-refresh mode on at91
   - Fixing RTC interrupt numbers on Exynos3250
   - Fixing a cache-coherency issues in CPU power-down on Exynos5
   - Multiple small OMAP power management fixes"
