Merge tag 'samsung-soc-4.6-2' of git://git.kernel.org/pub/scm/linux/kernel/git/krzk/linux into next/soc
Samsung Exynos (and older platforms) improvements for v4.6:
1. Split out Exynos PMU driver implementation from arm/mach-exynos
to the drivers/soc/samsung which will allow re-use of it on ARM64.
2. Use generic DT cpufreq driver on Exynos542x/5800.
3. Minor cleanups.
