Please take a look at the series with subject: "[PATCH 00/60] drm/omap: Replace custom display drivers with drm_bridge and drm_panel" Link: https://patchwork.kernel.org/cover/11034175/ Laurent has done a great job explaining the background, If you look into the patched you will see the idea is that a drm_panel no longer get attached to a drm_controller - it will be an argument to get_modes().
