[PATCH v2 08/23] drm/rcar-du: Merge LVDS and VGA encoder code
Laurent Pinchart
laurent.pinchart+renesas at ideasonboard.com
Wed Jul 31 06:21:52 PDT 2013
Create a single rcar_du_encoder structure that implements a KMS encoder.
The current implementation is straightforward and only configures CRTC
output routing.
