From bfce552d0b10e8fd79e703c67c084b4cf89ad68a Mon Sep 17 00:00:00 2001 From: Pankaj Dubey Date: Fri, 18 Dec 2015 09:02:16 +0530 Subject: drivers: soc: Add support for Exynos PMU driver This patch moves Exynos PMU driver implementation from "arm/mach-exynos" to "drivers/soc/samsung". This driver is mainly used for setting misc bits of register from PMU IP of Exynos SoC which will be required to configure before Suspend/Resume. Currently all these settings are done in "arch/arm/mach-exynos/pmu.c" but moving ahead for ARM64 based SoC support, there is a need of this PMU driver in driver/* folder. This driver uses existing DT binding information and there should be no functionality change in the supported platforms.
