read DMA.

+ The 1st RDMA is also used to be a controller node in Media Data
Path 3(MDP3)

Hi Rob,
Apologize for the misunderstanding with your comments in version 12, I
will recheck and delete the SW related information.
Thanks,
Moudy
Hello Moudy,
As an afterthought, I think that a commit title like
dt-bindings: mediatek: Add bindings for MediaTek MDP3 components
would be explaining what you're doing in a more concise manner.

Angelo
