With it here, we're going to validate the nodes twice as well. Same can be said for 'port' though. It can't be extended though. I originally wanted to a do a meta-schema to enforce some of this, but there's just too many exceptions. Rob

Yes, which I hope the device schema (using this panel-common) will narrow with additionalProperties: false. I can make it explicit: additionalProperties: true. Otherwise, how do I allow custom properties like: Documentation/devicetree/bindings/display/panel/advantech,idk-2121wr.yaml > >> + >> + required: >> + - port@0 >> + > > I don't think this should be added here because users must define what > each port is.

So you propose to drop entire "ports" here and expect every panel schema to define it instead? Best regards, Krzysztof

If neither of those are true, then they can use just 'port'. Otherwise, all those panel bindings already have to define the port nodes already. Rob

Few panel bindings for dual-link connections just type "ports: true", which does not enforce any type. Add common definition of ports, so the type will be fixed.
