The name of the file should be in the format vendor,compatible. In
this case is a bit complicated as there are different compatibles but
at least i'd use a generic name, i.e "mediatek,mtk-mdp3"

Remember to also change the name here.

These are all different h/w blocks, right? I think they should be 
separate schema files.

We generally don't do indices in DT, so explain why this is needed or 
come up with another way (and aliases is not it).
