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.

I typically run dt_bindings_check with DT_SCHEMA_FILES=... because running the whole thing takes longer than compiling a kernel from scratch. It seems I neglected to run it on the affected schemas. --Sean
