Subject: [PATCH v7 4/6] ARM: EXYNOS: split up exynos5250 SoC specific PMU data
Date: Fri, 18 Dec 2015 09:02:14 +0530 [thread overview]
Message-ID: <1450409536-30463-5-git-send-email-pankaj.dubey@samsung.com> (raw)
In-Reply-To: <1450409536-30463-1-git-send-email-pankaj.dubey@samsung.com>
This patch splits up mach-exynos/pmu.c file, and moves exynos5250,
PMU configuration data and functions handing data into exynos5250
SoC specific PMU file mach-exynos/exynos5250-pmu.c.
