Merge tag 'tags/cleanup2-3.15' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull ARM SoC late cleanups from Arnd Bergmann: "These could not be part of the first cleanup branch, because they either came too late in the cycle, or they have dependencies on other branches. Important changes are: - The integrator platform is almost multiplatform capable after some reorganization (Linus Walleij) - Minor cleanups on Zynq (Michal Simek) - Lots of changes for Exynos and other Samsung platforms, including further preparations for multiplatform support and the clocks bindings are rearranged" * tag 'tags/cleanup2-3.15' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (54 commits) devicetree: fix newly added exynos sata bindings ARM: EXYNOS: Fix compilation error in cpuidle.c ARM: S5P64X0: Explicitly include linux/serial_s3c.h in mach/pm-core.h ARM: EXYNOS: Remove hardware.h file ARM: SAMSUNG: Remove hardware.h inclusion ARM: S3C24XX: Remove invalid code from hardware.h dt-bindings: clock: Move exynos-audss-clk.h to dt-bindings/clock ARM: dts: Keep some essential LDOs enabled for arndale-octa board ARM: dts: Disable MDMA1 node for arndale-octa board ARM: S3C64XX: Fix build for implicit serial_s3c.h inclusion serial: s3c: Fix build of header without serial_core.h preinclusion ARM: EXYNOS: Allow wake-up using GIC interrupts ARM: EXYNOS: Stop using legacy Samsung PM code ARM: EXYNOS: Remove PM initcalls and useless indirection ARM: EXYNOS: Fix abuse of CONFIG_PM ARM: SAMSUNG: Move s3c_pm_check_* prototypes to plat/pm-common.h ARM: SAMSUNG: Move common save/restore helpers to separate file ARM: SAMSUNG: Move Samsung PM debug code into separate file ARM: SAMSUNG: Consolidate PM debug functions ARM: SAMSUNG: Use debug_ll_addr() to get UART base address ...
