Merge tag 'cleanup-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull ARM SoC cleanups from Olof Johansson: "This branch contains code cleanups, moves and removals for 3.13. Qualcomm msm targets had a bunch of code removal for legacy non-DT platforms. Nomadik saw more device tree conversions and cleanup of old code. Tegra has some code refactoring, etc. One longish patch series from Sebastian Hasselbarth changes the init_time hooks and tries to use a generic implementation for most platforms, since they were all doing more or less the same things. Finally the "shark" platform is removed in this release. It's been abandoned for a while and nobody seems to care enough to keep it around. If someone comes along and wants to resurrect it, the removal can easily be reverted and code brought back. Beyond this, mostly a bunch of removals of stale content across the board, etc" * tag 'cleanup-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (79 commits) ARM: gemini: convert to GENERIC_CLOCKEVENTS ARM: EXYNOS: remove CONFIG_MACH_EXYNOS[4, 5]_DT config options ARM: OMAP3: control: add API for setting IVA bootmode ARM: OMAP3: CM/control: move CM scratchpad save to CM driver ARM: OMAP3: McBSP: do not access CM register directly ARM: OMAP3: clock: add API to enable/disable autoidle for a single clock ARM: OMAP2: CM/PM: remove direct register accesses outside CM code MAINTAINERS: Add patterns for DTS files for AT91 ARM: at91: remove init_machine() as default is suitable ARM: at91/dt: split sama5d3 peripheral definitions ARM: at91/dt: split sam9x5 peripheral definitions ARM: Remove temporary sched_clock.h header ARM: clps711x: Use linux/sched_clock.h MAINTAINERS: Add DTS files to patterns for Samsung platform ARM: EXYNOS: remove unnecessary header inclusions from exynos4/5 dt machine file ARM: tegra: fix ARCH_TEGRA_114_SOC select sort order clk: nomadik: fix missing __init on nomadik_src_init ARM: drop explicit selection of HAVE_CLK and CLKDEV_LOOKUP ARM: S3C64XX: Kill CONFIG_PLAT_S3C64XX ASoC: samsung: Use CONFIG_ARCH_S3C64XX to check for S3C64XX support ...
