Pull ARM SoC fixes from Arnd Bergmann:
 "Here are a couple last-minute fixes for ARM SoCs.  Most of them are
  for the OMAP platforms, the rest are all for different platforms.

  OMAP:
     All dts fixes, mostly affecting voltages and pinctrl for various
     device drivers:

      - Regulator minimum voltage fixes for omap5
      - ISP syscon register offset fix for omap3
      - Fix regulator initial modes for n900
      - Fix omap5 pinctrl wkup instance size

  Allwinner:
     Remove incorrect constraints from a dcdc1 regulator

  Alltera SoCFPGA:
     Fix compilation in thumb2 mode

  Samsung exynos:
     Fix a potential oops in the pm-domain error handling

  Davinci:
     Avoid a link error if NVMEM is disabled

  Renesas:
     Do not mark an external uart clock as disabled, to allow probing
     the uarts"

* tag 'fixes-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc:
  ARM: davinci: only use NVMEM when available
  ARM: SoCFPGA: Fix secondary CPU startup in thumb2 kernel
  ARM: dts: omap5: fix range of permitted wakeup pinmux registers
  ARM: dts: omap3-n900: Specify peripherals LDO regulators initial mode
  ARM: dts: omap3: Fix ISP syscon register offset
  ARM: dts: omap5-cm-t54: fix ldo1_reg and ldo4_reg ranges
  ARM: dts: omap5-board-common: fix ldo1_reg and ldo4_reg ranges
  arm64: dts: r8a7795: Don't disable referenced optional scif clock
  ARM: EXYNOS: Properly skip unitialized parent clock in power domain on
  ARM: dts: sun8i-q8-common: Do not set constraints on dc1sw regulator
