[PATCH v2 5/6] ARCH: EXYNOS: split up exynos5420 SoC specific PMU data
From: Pankaj Dubey
Date: Wed Jan 07 2015 - 00:39:45 EST
This patch splits up mach-exynos/pmu.c file, and moves exynos5420,
PMU configuration data and functions handing data into exynos5420
SoC specific PMU file mach-exynos/exynos5420-pmu.c.
