This property has no default, and the property is not required. Is one
of these modes the default, or is there another mode beyond what's here
that is used if the property is absent? Or are all modes allowed with no
property?

The general approach the regulator API takes with everything is that if
there is no explict configuration then it will simply not touch the
hardware.  If nothing is configured then the hardware will be left in
whatever state we found it in which could be anything as far as we know,
it might vary depending on what was running before and what it was doing.

Okay, thanks for explaining Mark.
