This check can fail if there are any dependencies. 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.
