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" * tag 'late-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (60 commits) ARM: dts: vexpress: Add CCI node to TC2 device-tree ARM: EXYNOS: Skip C1 cpuidle state for exynos5440 ARM: EXYNOS: always enable PM domains support for EXYNOS4X12 ARM: highbank: clean-up some unused includes ARM: sun7i: Enable the A20 clocks in the DTSI ARM: sun6i: Enable clock support in the DTSI ARM: sun5i: dt: Use the A10s gates in the DTSI ARM: at91: at91_dt_defconfig: enable rm9200 support ARM: dts: add ADC device tree node for exynos5420/5250 ARM: dts: Add RTC DT node to Exynos5420 SoC ARM: dts: Update the "status" property of RTC DT node for Exynos5250 SoC ARM: dts: Fix the RTC DT node name for Exynos5250 irqchip: mmp: avoid to include irqs head file ARM: mmp: avoid to include head file in mach-mmp irqchip: mmp: support irqchip irqchip: move mmp irq driver ARM: OMAP: AM33xx: clock: Add RNG clock data ARM: OMAP: TI81XX: add always-on powerdomain for TI81XX ARM: OMAP4: clock: Lock PLLs in the right sequence ARM: OMAP: AM33XX: hwmod: Add hwmod data for debugSS ...
