Merge tag 'samsung-soc-4.6-2' of... 

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.

* tag 'samsung-soc-4.6-2' of git://git.kernel.org/pub/scm/linux/kernel/git/krzk/linux:
  ARM: s3c24xx: Avoid warning for inb/outb
  ARM: SAMSUNG: Remove unused register offset definition
  ARM: EXYNOS: Cleanup header files inclusion
  drivers: soc: samsung: Enable COMPILE_TEST
  MAINTAINERS: Add maintainers entry for drivers/soc/samsung
  drivers: soc: Add support for Exynos PMU driver
  ARM: EXYNOS: Split up exynos5420 SoC specific PMU data
  ARM: EXYNOS: Split up exynos5250 SoC specific PMU data
  ARM: EXYNOS: Split up exynos4 SoC specific PMU data
  ARM: EXYNOS: Split up exynos3250 SoC specific PMU data
  ARM: EXYNOS: Move pmu specific headers under "linux/soc/samsung"
  ARM: EXYNOS: Correct header comment in Kconfig file
  ARM: EXYNOS: Use generic cpufreq driver for Exynos5422/5800
  ARM: EXYNOS: Use generic cpufreq driver for Exynos5420
  ARM: s3c64xx: use "depends on" instead of "if" after prompt
  ARM: plat-samsung: use to_platform_device()
  ARM: EXYNOS: Code cleanup in map.h
  ARM: EXYNOS: Remove unused static mapping of CMU for exynos5
