The BCM283x SoCs have a display pipeline composed of several controllers
with device tree bindings that are supported by Linux.

Now that we have the DT validation in place, let's split into separate
files and convert the device tree bindings for those controllers to
schemas.

Yeah, that was fixed in patch 31 ("dt-bindings: display: vc4: dsi: Add
missing clock properties"). I'm not quite sure what the preferred
approach here would be: I did a conversion as is of the binding, and
then fixed it, or do you prefer having it all in the same patch?
