[v12,1/3] dt-binding: mt8183: add Mediatek MDP3 dt-bindings
Commit Message
This patch adds DT binding documents for Media Data Path 3 (MDP3)
a unit in multimedia system combined with several components and
used for scaling and color format convert.
It can create multiple paths with different functions by assigning
different components, a simple diagram is as follows:

Sure seems like you should be using the OF graph binding to describe
these connections unless all the sub-blocks and their connections are
fixed across different SoCs.

This does not make sense as a compatible entry. The first string should
be more specific than the 2nd string. The controller node is a different
instance of the RDMA block or some s/w designation? Looks like the
latter to me...

Note that if there's only 1 instance of these blocks, you can just find
them by compatible and don't need a property.
