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

yamllint warnings/errors:

dtschema/dtc warnings/errors:

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.

==> I set the patch file "mt8195-pinfunc.h" patch in "4/6". so we should
add the file "mt8195-pinfunc.h" in this patch ? or we should put it
before this patch(2/6)?

Thanks.

It is part of the binding, so it belongs in this patch.
