From 049d34e94f9aa2c3ed22a7bad75dd188ec7dacb9 Mon Sep 17 00:00:00 2001 From: Rahul Sharma Date: Tue, 20 May 2014 10:36:05 +0530 Subject: drm/exynos: use regmap interface to set hdmiphy control bit in pmu Exynos drm hdmi driver used to get dummy hdmiphy clock to control the PMU bit for hdmiphy. This bit needs to be set before setting any resolution to hdmi hardware. This was handled using dummy hdmiphy clock which is removed here. PMU is already defined as system controller for exynos SoCs. Hdmi driver is modified to control the phy enable bit inside PMU using regmap interfaces. Devicetree binding document for hdmi is also updated.
