The graph schema should already check this case with this subschema: oneOf: - required: - port - required: - "#address-cells" - "#size-cells" However, I now see this would allow port and #address-cells if #size-cells is omitted. (#address-cells is a dependency for ##size-cells, but not vice-versa because interrupt-controllers can have ##just #address-cells). Perhaps this should instead be: oneOf: - required: - port - anyOf: - required: - "#address-cells" - required: - "#size-cells" We're missing a similar check on endpoint. Or I'm forgetting why I didn't add it. I suspect there are a lot more cases if we fixed these in the users. Rob
