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.

Add two compatibles for binman entries, as a starting point for the schema. Note that, after discussion on v2, we decided to keep the existing meaning of label so as not to require changes to existing userspace software when moving to use binman nodes to specify the firmware layout. Note also that, after discussion on v6, we decided to use the same 'fixed-partition' schema for the binman features, so this version adds a new 'binman.yaml' file providing the new compatibles to the existing partition.yaml binding.
