Same as what was earlier passed by using the
"supply_regulator" field of regulator_init_data structure.
Grant wanted the bindings to support specifying multiple parents
and hence I was thinking of either a list of names *or*
a list of phandles to specify multiple parents to a regulator.

So, as I'm fairly sure I said last time these are just standard
supplies.  It just happens to be that the consumer is a regulator.  The
fact that Linux chooses to have core framework handling for this is an
implementation detail of Linux (and indeed many devices ignore this for
their on board regulators).
