It should be most specific to least specific from left to right. I'd
rather see "qcom,sc7180-dp" dropped entirely as it will become important
to know that sc7280 has eDP and DP whereas sc7180 only has DP. We should
key that knowledge off the compatible string, so having sc7180-dp here
makes that harder, not easier.

It's only the DRM tree that want the changelog above '---', please move
it down.

Also, why isn't this "patch n/3" if there's three patches?

This block seems to be indented with spaces?

Prefixing the labels of all the mdss children mdss_ instead has the
benefit that the nodes group naturally in the board dts.

This isn't a sc7180-dp block.

There seems to be some spaced among the tabs here.

Same here, seems to be some spaces among the tabs on both of these
lines.

This seems to be indented with spaces?
