Merge tag 'pm-merge' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull ARM SoC power management and clock changes from Olof Johansson: "This branch contains a largeish set of updates of power management and clock setup. The bulk of it is for OMAP/AM33xx platforms, but also a few around hotplug/suspend/resume on Exynos. It includes a split-up of some of the OMAP clock data into separate files which adds to the diffstat, but gross delta is fairly reasonable." * tag 'pm-merge' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (60 commits) ARM: OMAP: Move plat-omap/dma-omap.h to include/linux/omap-dma.h ASoC: OMAP: mcbsp fixes for enabling ARM multiplatform support watchdog: OMAP: fixup for ARM multiplatform support ARM: EXYNOS: Add flush_cache_all in suspend finisher ARM: EXYNOS: Remove scu_enable from cpuidle ARM: EXYNOS: Fix soft reboot hang after suspend/resume ARM: EXYNOS: Add support for rtc wakeup ARM: EXYNOS: fix the hotplug for Cortex-A15 ARM: OMAP2+: omap_device: Correct resource handling for DT boot ARM: OMAP2+: hwmod: Add possibility to count hwmod resources based on type ARM: OMAP2+: hwmod: Add support for per hwmod/module context lost count ARM: OMAP2+: PRM: initialize some PRM functions early ARM: OMAP2+: voltage: fixup oscillator handling when CONFIG_PM=n ARM: OMAP4: USB: power down MUSB PHY during boot ARM: OMAP2+: clock: Cleanup !CONFIG_COMMON_CLK parts ARM: OMAP2xxx: clock: drop obsolete clock data ARM: OMAP2: clock: Cleanup !CONFIG_COMMON_CLK parts ARM: OMAP3+: DPLL: drop !CONFIG_COMMON_CLK sections ARM: AM33xx: clock: drop obsolete clock data ARM: OMAP3xxx: clk: drop obsolete clock data ...
