For now I'm going to stick with the old convention and make port 0 optional,
when the bridge is a DSI child and LVDS port 1 mandatory.
The current policy does not seem to have been changed. There's a quiet new binding,
which follows the old convention:
Documentation/devicetree/bindings/connector/usb-connector.txt
If you can find an example of new bindings, which follow your convention and you
convince Rob, then I'll be completely okay with it and I'll change it the way
you propose.
