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."
