[PATCH v3 07/10] drm: rcar-du: Skip LVDS1 output on Gen3 when using dual-link LVDS mode

2019-05-28 Thread Laurent Pinchart
In dual-link LVDS mode, the LVDS1 encoder is used as a companion for LVDS0, and both encoders transmit data from DU0. The LVDS1 output of DU1 can't be used in that case, don't create an encoder and connector for it. Signed-off-by: Laurent Pinchart Reviewed-by: Jacopo Mondi Tested-by: Jacopo
