1. Your patches are not properly threaded which makes it difficult to
review and handle them. Resend with proper threads.

2. Subject: drop second, redundant "binding for".

Does not look like you tested the bindings. Please run `make
dt_binding_check` (see
Documentation/devicetree/bindings/writing-schema.rst for instructions).

This should be rather unevaluatedProperties: false, otherwise you do not
allow any other properties, except compatible. Was this the intention?

Best regards,

Are you going to test it, before sending?

Best regards,

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/leds/backlight/kinetic,ktz8866.yaml: properties:compatible:items: {'const': 'kinetic,ktz8866'} is not of type 'array'
	from schema $id: http://devicetree.org/meta-schemas/string-array.yaml#

doc reference errors (make refcheckdocs):

See https://patchwork.ozlabs.org/project/devicetree-bindings/patch/20221221070216.17850-1-lujianhua000@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.

I have resent a new patch and gotten rip of errors of the old dt-binding yaml.
