A different dependency should be noted in *this* patch. 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 after running the above command yourself. Note that DT_SCHEMA_FILES can be set to your schema file to speed up checking your schema. However, it must be unset to test all examples with your schema.

The "dt-bindings" prefix is already stating that these are bindings.

Why doing something entirely different then entire Linux kernel? Do not use downstream as template, that's a no go. Best regards, Krzysztof
