I am wondering which of the flags make sense for eDP and how the bus
format should be described?
Some eDP panels seems [1] to specify DRM_BUS_FLAG_DATA_MSB_TO_LSB and
DRM_BUS_FLAG_SYNC_DRIVE_NEGEDGE, but I am not sure what sense they make
for packet data with embedded clock that eDP uses? (Unless, of course,
my understanding of eDP is entirely missing the point.)
This panel uses RGB888 data over two differential pairs. Would
format = MEDIA_BUS_FMT_RGB888_1X24 be appropriate?
