Please use subject prefixes matching the subsystem. You can get them for
example with `git log --oneline -- DIRECTORY_OR_FILE` on the directory
your patch is touching.

A nit, subject: drop second/last, redundant "bindings documentation
yaml". The "dt-bindings" prefix is already stating that these are
bindings. Quite redundant/useless subject.

Drop "Bindings for" and instead describe the hardware. Don't copy the
title, what's the point in this?

No, that won't work. Your schema is not being applied. Look at patches
on the mailing list for the phys.

Why do I see multiple patchsets of this?

Best regards,
