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:

Follow DTS coding style in properties order and everything around here.

I can do it for most of the properties, but is there any other rules 
other than sort,

eg. compatible and reg in the beginning and status in the end?
