Hi Rob,

Thanks for the steps. I seeing minimum version error, though the dtschema is latest.

$ make dt_binding_check
sort: -:2: disorder: 0
ERROR: dtschema minimum version is v2021.2.1
Documentation/devicetree/bindings/Makefile:12: recipe for target 'check_dtschema_version' failed
make[1]: *** [check_dtschema_version] Error 1
Makefile:1418: recipe for target 'dt_binding_check' failed
make: *** [dt_binding_check] Error 2

$ pip3 show dtschema

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.
