Merge tag 'cleanup-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull ARM SoC cleanup from Olof Johansson: "Here is a collection of cleanup patches. Among the pieces that stand out are: - The deletion of h720x platforms - Split of at91 non-dt platforms to their own Kconfig file to keep them separate - General cleanups and refactoring of i.MX and MXS platforms - Some restructuring of clock tables for OMAP - Convertion of PMC driver for Tegra to dt-only - Some renames of sunxi -> sun4i (Allwinner A10) - ... plus a bunch of other stuff that I haven't mentioned" * tag 'cleanup-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (119 commits) ARM: i.MX: remove unused ARCH_* configs ARM i.MX53: remove platform ahci support ARM: sunxi: Rework the restart code irqchip: sunxi: Rename sunxi to sun4i irqchip: sunxi: Make use of the IRQCHIP_DECLARE macro clocksource: sunxi: Rename sunxi to sun4i clocksource: sunxi: make use of CLKSRC_OF clocksource: sunxi: Cleanup the timer code ARM: at91: remove trailing semicolon from macros ARM: at91/setup: fix trivial typos ARM: EXYNOS: remove "config EXYNOS_DEV_DRM" ARM: EXYNOS: change the name of USB ohci header ARM: SAMSUNG: Remove unnecessary code for dma ARM: S3C24XX: Remove unused GPIO drive strength register definitions ARM: OMAP4+: PM: Restore CPU power state to ON with clockdomain force wakeup method ARM: S3C24XX: Removed unneeded dependency on CPU_S3C2412 ARM: S3C24XX: Removed unneeded dependency on CPU_S3C2410 ARM: S3C24XX: Removed unneeded dependency on ARCH_S3C24XX for boards ARM: SAMSUNG: Fix typo "CONFIG_SAMSUNG_DEV_RTC" ARM: S5P64X0: Fix typo "CONFIG_S5P64X0_SETUP_SDHCI" ...

+Allwinner Sunxi Interrupt Controller
+
+Required properties:
+
+- compatible : should be "allwinner,sun4i-ic"
+- reg : Specifies base physical address and size of the registers.
+- interrupt-controller : Identifies the node as an interrupt controller
+- #interrupt-cells : Specifies the number of cells needed to encode an
+ interrupt source. The value shall be 1.
