From 7341c3080649c98d470f326d0239dde2c1912059 Mon Sep 17 00:00:00 2001 From: Tomasz Stanislawski Date: Thu, 3 Oct 2013 16:04:53 +0200 Subject: [PATCH] drm: exynos: hdmi: use hdmiphy as PHY The HDMIPHY (physical interface) is controlled by a single bit in a power controller's regiter. It was implemented as clock. It was a simple but effective hack. This patch makes HDMI driver to control HDMIPHY via PHY interface.
