Commit Message

  Almost every compatible string in the CCI driver is a duplicate. Adjust
the bindings to include a common (first-soc-implementing-vX) compatible
to remove the need to keep adding superfluous compatible strings.

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/i2c/qcom,i2c-cci.example.dtb: cci@ac4a000: compatible: 'oneOf' conditional failed, one must be fixed:
	['qcom,sdm845-cci'] is too short
	'qcom,sdm845-cci' is not one of ['qcom,msm8226-cci', 'qcom,msm8974-cci', 'qcom,msm8996-cci']

See https://patchwork.ozlabs.org/project/devicetree-bindings/patch/20221213115628.105149-1-konrad.dybcio@linaro.org

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.

Except missing test, how about also adding a comment to the driver, that
list of compatibles should not grow when not needed?

Best regards,

Hm? I tested this locally with dt_binding_check and it passed..
