Perhaps it would be better to centralise the documentation inclusive
of the regulator contingent. Or at least provide a _full_ example in
each document.
Ok.

Why aren't you using 'regulator-compatible'?
I referred tps65217.txt the predecessors and used the compatible.
I also referred twl-regulator.txt.
+Optional properties:
+- Any optional property defined in bindings/regulator/regulator.txt

+Example:

Genuine question: Is the @0 meaningful?
@0 is not the best example. @24 is what i use on the am43x.
I will change it to @24.

Thanks for reviewing.
