Use subject prefixes matching the subsystem (which you can get for example with `git log --oneline -- DIRECTORY_OR_FILE` on the directory your patch is touching). Missing: 's' Subject: drop second/last, redundant "dt-binding documents". The "dt-bindings" prefix is already stating that these are bindings and documentation.
