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

yamllint warnings/errors:

See https://patchwork.ozlabs.org/project/devicetree-bindings/patch/20250813042331.1258272-9-hans.zhang@xxxxxxxxxxx

The base for the series is generally the latest rc1. A different dependency
should be noted in *this* patch.

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 after running the above command yourself. Note
that DT_SCHEMA_FILES can be set to your schema file to speed up checking
your schema. However, it must be unset to test all examples with your schema.


Dear Rob,

I'm very sorry. No errors were detected on my PC. I'll check my local
environment and fix this issue in the next version.

If I have done anything wrong, please remind me.

DT_SCHEMA_FILES limits testing to only the matching pattern.
Ultimately, you have to test without it.


Dear Rob,

Thank you very much for your reply and reminder. I will check it carefully again.

Best regards,
