Pull ARM SoC fixes from Arnd Bergmann:
 "Nothing frightening this time, just smaller fixes in a number of
  places.

  The other changes contained here are:

   MAINTAINERS file updates:

   - The mach-gemini maintainer is back in action and has a new git tree

   - Krzysztof Kozlowski has volunteered to be a new co-maintainer for
     the samsung platforms

   - updates to the files that belong to Marvell mvebu

  Bug fixes:

   - The largest changes are on omap2, but are only to avoid some
     harmless warnings and to fix reset on omap4

   - a small regression fix on tegra

   - multiple fixes for incorrect IRQ affinity on vexpress

   - the missing system controller on arm64 juno is added

   - one revert of a patch that was accidentally applied twice for
     mach-rockchip

   - two clock related DT fixes for mvebu

   - a workaround for suspend with old DT binaries on new exynos kernels

   - Another fix for suspend on exynos, needs to be backported"

* tag 'fixes-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (21 commits)
