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.

This is an attempt to rewrite the Marvell MV88E6xxx switch bindings in YAML schema. The current text binding says: WARNING: This binding is currently unstable. Do not program it into a FLASH never to be changed again. Once this binding is stable, this warning will be removed. Well that never happened before we switched to YAML markup, we can't have it like this, what about fixing the mess?
