The base for a patch series is generally the most recent rc1. If you already ran 'make dt_binding_check' and didn't see the above error(s), then make sure 'yamllint' is installed and dt-schema is up to date: pip3 install dtschema --upgrade Please check and re-submit.

Should I change the order of the patchset (let the yaml pathc behind the header) to fixed that ?

DT headers should be part of the binding schema patch. (Or at least come first). Rob
