Why? Wasn't it there before?

Please use standard email subjects, so with the PATCH keyword in the
title. `git format-patch` helps here to create proper versioned patches.
Another useful tool is b4. Skipping the PATCH keyword makes filtering of
emails more difficult thus making the review process less convenient.

Don't write it by yourself....

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:

Nope, just write the description as items in clocks, instead of
maxItems. And drop clock-names, not needed and kind of obvious.


Best regards,

Earlier we used to enable all PL clocks (fixed), now we want to enable 
only the needed clocks.
