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.

Move the existing allOf *above* unevaluatedProperties:false (like in example-schema). 2. Drop the quotes around 'watchdog.yaml', when moving. 3. Add your pieces. All above in one commit.
