Message-id: <1398687607-4554-4-git-send-email-pankaj.dubey@samsung.com> Date: Mon, 28 Apr 2014 21:20:07 +0900 From: Pankaj Dubey <pankaj.dubey@...sung.com> To: linux-samsung-soc@...r.kernel.org, linux-kernel@...r.kernel.org, linux-arm-kernel@...ts.infradead.org Cc: kgene.kim@...sung.com, linux@....linux.org.uk, t.figa@...sung.com, chow.kim@...sung.com, yg1004.jang@...sung.com, vikas.sajjan@...sung.com, b.zolnierkie@...sung.com, Pankaj Dubey <pankaj.dubey@...sung.com>, Sangbeom Kim <sbkim73@...sung.com>, Samuel Ortiz <sameo@...ux.intel.com>, Lee Jones <lee.jones@...aro.org> Subject: [RESUBMIT RFC PATCH v2 3/3] drivers: mfd: Add support for Exynos PMU driver This patch moves Exynos PMU driver implementation from "arm/mach-exynos" to "drivers/mfd". 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 DT based implementation of PMU driver. This driver uses already existing DT binding information.
