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:
 -  multiple omap2+ bug fixes
 - a regression on ux500 dt support
 - a build failure on shmobile

* tag 'fixes-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc:
  ARM: OMAP2+: omap2plus_defconfig: EHCI driver is not stable, disable it
  ARM: shmobile: fix platsmp.c build when ARCH_SH73A0=n
  ARM: ux500: Over-ride the DT device naming scheme for pinctrl
  ARM: ux500: Fix build errors/warnings when MACH_UX500_DT is not set
  of: address: Don't fail a lookup just because a node has no reg property
  ARM: OMAP2+: hwmod code/clockdomain data: fix 32K sync timer
