My bot found errors running 'make DT_CHECKER_FLAGS=-m dt_binding_check'

\ndoc reference errors (make refcheckdocs):

This check can fail if there are any dependencies. 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.
