The name field should be set to something that is usefully descriptive

for the board for configuration of supplies for other regulators and

for use in logging and other diagnostic output.  Normally the name

used for the supply rail in the schematic is a good choice.  If no

name is provided then the subsystem will choose one.



Regulator-1 supplies power to Regulator-2. This relationship must be registered

with the core so that Regulator-1 is also enabled when Consumer A enables its

supply (Regulator-2). The supply regulator is set by the supply_regulator

	  This driver provides support for regulators that can be

	  controlled via gpios.

	  It is capable of supporting current and voltage regulators

	  and the platform has to provide a mapping of GPIO-states
