My bot found errors running 'make DT_CHECKER_FLAGS=-m dt_binding_check'
on your patch (DT_CHECKER_FLAGS is new in v5.13):

yamllint warnings/errors:

dtschema/dtc warnings/errors:
/builds/robherring/dt-review-ci/linux/Documentation/devicetree/bindings/hwmon/amphenol,chipcap2.example.dtb: humidity@28: compatible: 'oneOf' conditional failed, one must be fixed:
	['amphenol,cc2d23s'] is too short
	'amphenol,cc2d23' was expected
	from schema $id: http://devicetree.org/schemas/hwmon/amphenol,chipcap2.yaml#

doc reference errors (make refcheckdocs):

See https://patchwork.ozlabs.org/project/devicetree-bindings/patch/20231020-topic-chipcap2-v4-4-7940cfa7613a@gmail.com

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.

Sorry for that, I did a last-minute modification to comply with the
changes in the driver and I forgot to check the bindings again.
Definitely something to avoid in the the future.

Adding the const "amphenol,cc2d23" to the compatible property fixes the
issue and passes the tests, so I will include it in the next version.

Best regards,
Javier Carrasco
