[PATCH v3 55/56] drm/omap: remove dispc_ops

Tomi Valkeinen
2020-11-05T12:06:19Z

dispc_ops was created to help with the multi-module architecture and
giving us the possibility of multiple dispc implementations. Neither of
these is valid anymore, and we can remove dispc_ops and use direct
calls to dispc.
