The TPD12S015, OPA362 and analog and HDMI connectors are now supported by DRM bridge drivers, and the omapdrm HDMI and VENC outputs can be handled through the drm_bridge API. Switch the outputs to drm_bridge by making the next bridge mandatory and removing the related omapdrm-specific display drivers.
