DM_VIDEO migration deadline is already expired, but around 80 Allwinner boards are still using video in a legacy way: ===================== WARNING ====================== This board does not use CONFIG_DM_VIDEO Please update the board to use CONFIG_DM_VIDEO before the v2019.07 release. Failure to update by the deadline may result in board removal. See doc/driver-model/migration.rst for more info. ==================================================== Convert the legacy video driver over to the DM_VIDEO framework. This is a minimal conversion: it doesn't use the DT for finding its resources, nor does it use DM clocks or DM devices for the outputs (LCD, HDMI, CVBS). Tested in Bananapi M1+ Plus 1920x1200 HDMI out.
