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).

Just a hint - I in general ignore all the emails without dt-bindings prefix.
Ok, I'll prefix it "dt-bindings: regulator:"

Drop quotes.

Why do you need entire "regulators" node for one regulator? Why do you
need child at first place. Drop it entirely.
I will remove the regulators node. I think the vout node is needed to get the of_get_regulator_init_data.

You missed that piece of explanation:

"The set of possible operating modes depends on the capabilities of
every hardware so each device binding documentation explains which
values the regulator supports."

Ok, I will add a description for the valid regulator-initial-mode values.

Thanks!

Kind regards
