Merge tag 'samsung-soc-4.6-2' of git://git.kernel.org/pub/scm/linux/k…

…ernel/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 Signed-off-by: Olof Johansson <olof@lixom.net>
