The panel is always fixed to port 1, isn't it? Shouldn't it be just
port@1 here?

Running 'make dtbs_check' with the schema in this patch gives the
following warnings. Consider if they are expected or the schema is
incorrect. These may not be new warnings.

Note that it is not yet a requirement to have 0 warnings for dtbs_check.
This will change in the future.

What you need is to just reference dsi-controller.yaml at the top level.

It's possible to attach something that doesn't use panel-common.yaml
and if it did, it would be applied by that schema.

It works, thank you.

Then we will also need to rename the "dsi-bridge" node to just "dsi" in
the new ASUS TF700T device-tree since dsi-controller.yaml wants that name.
