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"
