Please run `make > dt_binding_check` (see > Documentation/devicetree/bindings/writing-schema.rst for instructions). Apologies, wrong template. Correct comment: Does not look like you tested the DTS against bindings. Please run `make dtbs_check` (see Documentation/devicetree/bindings/writing-schema.rst for instructions).
