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().
