Feeling like a broken record, given I am leaving the same comments on
multiple patches. The commit message needs to explain why you're doing
something. I can read the diff and see what you did!

Same comment here as elsewhere.

The | here is not needed, there's no formatting to preserve.

From a quick check, most bindings with regulator subnodes restrict the
subnode names with patternproperties. Is there a reason you have not?

Why is this commented out? Please either restore it or remove it (with
justification).
