Subject: drop second, redundant "bindings".

Blank line.

Description is not a correct sentence. Description explains the hardware
property you have here.

Why maximum is 255? Why 0=100%? 0 should be equal to 0 and maximum to
some maximum value (e.g. 100%). If these are percents, use appropriate
units. If these are not - what are these? You need a $ref in such case.

doc reference errors (make refcheckdocs):
See https://patchwork.ozlabs.org/project/devicetree-bindings/patch/[email protected]
This check can fail if there are any dependencies. The base for a patch
series is generally the most recent rc1.
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.
