That's the important to explain here. It'd be really nice if you can explain a bit how do you test this driver and also explain the general architecture of this driver you have in mind. Why you are exposing the MDP HW directly as a V4L2 device to userspace, who needs that and why. > Signed-off-by: Ping-Hsun Wu > Signed-off-by: daoyuan huang > Signed-off-by: Moudy Ho > --- > Depend
