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.

Thanks for the information. It's my 1st time to write binding using yaml format, I hadn't noticed there was a checker can be used for sanity test. I will update and run the dt_binding_check at my side before uploading new patchset.
