I searched, and this is the only place that uses the hisi prefix. Currently, YAML check will report warnings due to mismatch any of the regexes defined in Documentation/devicetree/bindings/vendor-prefixes.yaml Is it not good to add hisi prefix to clear warnings? "^hisi,.*": description: Hisilicon Limited, deprecated. By the way, Hi Rob: The license information in some YAML files is incorrect. Can you correct it in v5.11?
