From 6f50e0758795e21919d0d45e3c9ff441f6139575 Mon Sep 17 00:00:00 2001 From: Alex Deucher Date: Mon, 17 Mar 2014 23:48:16 -0400 Subject: [PATCH] drm/radeon/atom: rework encoder enable/disable sequence MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit This more closely matches what the vbios does and also adds a quirk for travis lvds displays and powers down the sink on DP displays which saves some power and may fix display issues in some cases.
