From a5ec598650257d9a7abefa6616840c872e194fdb Mon Sep 17 00:00:00 2001 From: Vivek Gautam Date: Tue, 16 Sep 2014 10:32:06 +0530 Subject: phy: exynos-dp-video: Use syscon support to control pmu register Currently the DP_PHY_ENABLE register is mapped in the driver, and accessed to control power to the PHY. With mfd-syscon and regmap interface available at our disposal, it's wise to use that instead of using a 'reg' property for the controller and allocating a memory resource for that. To facilitate this, we have added another compatible string for Exynso5420 SoC to acquire driver data which contains different DP-PHY-CONTROL register offset.
