If you already ran 'make dt_binding_check' and didn't see the above
error(s), then make sure dt-schema is up to date:

pip3 install git+https://github.com/devicetree-org/dt-schema.git@master --upgrade

Please check and re-submit.

Hi Rob,

I could reproduce the error log after dt-schema updates to the latest
version.
I'll fix it in next version.

Thanks!
