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.

It is dt-bindings, not something else.

A nit, subject: drop second/last, redundant "bindings for". The
"dt-bindings" prefix is already stating that these are bindings. One
bindings is enough.

xx sound like wildcard which you should not use. If you open the product
page, it also suggests that.
