From 00b8e8ceece20db990b1fbb11f1d6051a276436b Mon Sep 17 00:00:00 2001 From: Alex Deucher Date: Wed, 5 Oct 2011 18:36:50 -0400 Subject: [PATCH] drm/radeon/kms: use hardcoded dig encoder to transmitter mapping for DCE4.1 commit cb7cf41961fe10773c491c75ae73539ad4bbed66 upstream. The encoders are supposedly fully routeable, but changing the mapping doesn't always seem to take. Using a hardcoded mapping is much more reliable.
