[PATCH 5/6] drm/msm/dp: migrate the ycbcr_420_allowed to drm_bridge
Posted by Dmitry Baryshkov 1 year, 3 months ago 
Instead of forcing the ycbcr_420_allowed flag to be set on the created
drm_connector, set it on the drm_bridge instance and allow
drm_bridge_connecgtor to propagate it to the drm_connector.
