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. For bindings, the preferred subjects are
explained here:
https://www.kernel.org/doc/html/latest/devicetree/bindings/submitting-patches.html#i-for-patch-submitters

A nit, subject: drop second/last, redundant "binding". The "dt-bindings"
prefix is already stating that these are bindings.
See also:
https://elixir.bootlin.com/linux/v6.17-rc3/source/Documentation/devicetree/bindings/submitting-patches.rst#L18

Please organize the patch documenting compatible (DT bindings) before
their user.

Please wrap code according to the preferred limit expressed in Kernel
coding style, so at 80.

Use existing property, git grep shunt.

And then test it...
