Hi Andy, Noralf,

gentle ping for this patch set,
do we have any new structure, or idea to support both dpi and dbi
interface by one drm panel driver?
from this thread
https://lists.freedesktop.org/archives/dri-devel/2020-May/267031.html
, it's seems
discussing was stopped at may 25.

if there are any new information about this topic, please feel free to
let me know. hope i can make some
progress on it.

thanks,

Dillon,

best regards
