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:
 "Most of the changes this time are for incorrect device nodes in
  various ways, on on imx, berlin, exynos, ux500, uniphier, omap and
  meson.

  Chen-Yu Tsai now co-maintains mach-sunxi (Allwinner).

  Other bug fixes include
   - a partial revert of a broken tegra gpio patch
   - irq affinity for arm ccn
   - suspend on one Armada 385 machine
   - enable ZONE_DMA to avoid an OMAP crash for over 2GB RAM
   - turning on a regulator on beagleboard-x15 for HDMI
   - making the omap gpmc debug code visible
   - setup of orion network switch
   - a rare build regression for pxa"
