From 3d05859fd78bbc0b04cca929aea494f5e6b8235b Mon Sep 17 00:00:00 2001 From: Inki Dae Date: Fri, 17 Aug 2012 18:35:47 +0900 Subject: drm/exynos: make sure that hardware overlay for hdmi is disabled the values set to registers will be updated into real registers at vsync so dma operation could be malfunctioned when accessed to memory after gem buffer was released. this patch makes sure that hw overlay is disabled before the gem buffer is released.

These pointers were expected from the plf data. Cleaned this dependency by exporting i/f which are called by hdmi, mixer driver probes for setting their context.
