You are describing a controller so here you should reference to nand-controller.yaml, but then prevent any property not defined in nand-controller.yaml from being used. In this case you probably want to try unevaluatedProperties: false, which means that any property not listed here or in the referenced schemas will be prohibited. Thanks, Miquèl
