[RFC][PATCH] drm/radeon/hdmi: use separated file for DCE 3.1+ hw
Rafał Miłecki

Mon May 12 06:54:21 PDT 2014
DCE 3.1 and 3.2 have different HDMI registers and should be programmed
in a slightly different way. Moving support to separated file will
allow use to use rv770d.h header in the future and adjust code as well.
