Use subject prefixes matching the subsystem (which you can get for
example with `git log --oneline -- DIRECTORY_OR_FILE` on the directory
your patch is touching).

Subject: drop second/last, redundant "bindings". The "dt-bindings"
prefix is already stating that these are bindings.


Best regards,
Krzysztof

Hi Krzysztof,

Thank you for the feedback.
I will change the subject line.

Regards,
Subhajit Ghosh

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:
Error: Documentation/devicetree/bindings/iio/light/avago,apds9306.example.dts:29.33-34 syntax error
FATAL ERROR: Unable to parse input tree

doc reference errors (make refcheckdocs):

See https://patchwork.ozlabs.org/project/devicetree-bindings/patch/20230411011203.5013-2-subhajit.ghosh@tweaklogic.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.

Hi Rob,
Thank you very much for reviewing the patch.

Thank you for the above steps, I did not perform them. It will
be fixed in the next revision.
