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.

Hi, Rob

Thank you for the error report and advice.
I will recheck DT binding.

Best regards
Tomohito Esaki

DRM is a Linuxism. What's virtual DRM? Why does it need to be in DT? 
What's the usecase? You're going to need a lot more reasoning to justify 
this for DT.
