[PATCH] drm/msm: convert to drm_bridge
Rob Clark
robdclark at gmail.com
Fri Aug 30 10:02:15 PDT 2013
Drop the msm_connector base class, and special calls to base class
methods from the encoder, and use instead drm_bridge. This allows for a
cleaner division between the hdmi (and in future dsi) blocks, from the
mdp block.
