Neither commit msg nor property describes the hardware feature. Please
describe the hardware, not OS behavior, in the property. Both in the
property name and in its description.

Please use scripts/get_maintainers.pl to get a list of necessary people
and lists to CC. It might happen, that command when run on an older
kernel, gives you outdated entries. Therefore please be sure you base
your patches on recent Linux kernel.

You missed at least devicetree list (maybe more), so this won't be
tested by automated tooling. Performing review on untested code might be
a waste of time, thus I will skip this patch entirely till you follow
the process allowing the patch to be tested.

Please kindly resend and include all necessary To/Cc entries.

Also, use proper order of patches - first bindings, then their user.

Best regards,
Krzysztof
