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

Pull ARM SoC late changes from Kevin Hilman:
 "These are changes that arrived a little late before the merge window,
  or had dependencies on previous branches.

  Highlights:
   - ux500: misc.  cleanup, fixup I2C devices
   - exynos: DT updates for RTC; PM updates
   - at91: DT updates for NAND; new platforms added to generic defconfig
   - sunxi: DT updates: cubieboard2, pinctrl driver, gated clocks
   - highbank: LPAE fixes, select necessary ARM errata
   - omap: PM fixes and improvements; OMAP5 mailbox support
   - omap: basic support for new DRA7xx SoCs"
