Please drop all mentions of drivers, bindings are for hardware.

Can drop the items: here since you only have one. The name is also
pretty pointless when you only have one...

Neither of the labels here are used AFAICT, please remove them.

Hi Conor,

thanks for the review.  I've taken into account your comment and
will push this into the v3.

Ok, I removed clock-names (from required as well).

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/media/st,stm32-dcmipp.yaml: title: 'STMicroelectronics STM32 DCMIPP Digital Camera Memory Interface Pixel Processor binding' should not be valid under {'pattern': '([Bb]inding| [Ss]chema)'}
	hint: Everything is a binding/schema, no need to say it. Describe what hardware the binding is for.
	from schema $id: http://devicetree.org/meta-schemas/base.yaml#

doc reference errors (make refcheckdocs):

See https://patchwork.ozlabs.org/project/devicetree-bindings/patch/20230829132357.192535-2-alain.volmat@foss.st.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.
