My bot found errors running 'make dt_binding_check' on your patch:

See https://patchwork.ozlabs.org/patch/1411582

The base for the patch is generally the last rc1. Any dependencies
should be noted.

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.
