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:
Documentation/devicetree/bindings/soc/qcom/qcom-pbs.example.dts:18.16-26.11: Warning (unit_address_vs_reg): /example-0/pmic@0: node has a unit name, but no reg or ranges property

doc reference errors (make refcheckdocs):

See https://patchwork.ozlabs.org/project/devicetree-bindings/patch/[e-mail]

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.

Again not tested.

Also, you missed comments. :(

This is a friendly reminder during the review process.

It seems my previous comments were not fully addressed. Maybe my
feedback got lost between the quotes, maybe you just forgot to apply it.
Please go back to the previous discussion and either implement all
requested changes or keep discussing them.

Thank you.


Best regards,
Krzysztof

Hi Krzysztof,

Sorry about the testing, found that my dt_binding_checker was out dated and that
is why it has not been picking up those dt_binding errors :/ 

I went back to take a look at the original comments I missed and just wanted to
list them for a quick double check.

1. Rename binding to be qcom,pbs so that it matches compatible
2. Include Soc specific compatibles i.e. 
   compatible:
     items:
       - enum:
         - qcom,pmi632-pbs
       - const: qcom,pbs
3. Fix the example node

Thanks,
Anjelique
