Since all boards use the same address, drop the goodix,hid-report-addr
property and hardcode it in the driver as a default value.

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

yamllint warnings/errors:

dtschema/dtc warnings/errors:


doc reference errors (make refcheckdocs):

See https://patchwork.ozlabs.org/project/devicetree-bindings/patch/20241108120311.87795-3-charles.goodix@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.

Where's the driver change?

I don't see the point in defining this and then removing it in the next 
patch.

Dropping a required property is an ABI break.

A devicetree that passes with the schema will not work on current 
kernels that require this property.

Apologies for the confusion. The driver changes will be included in the next version.

Thank you for pointing this out. The next version will include the
necessary driver modifications.
