+ Generic Voltage and Current Regulator support.
+
+ This framework is designed to provide a generic interface to voltage
+ and current regulators within the Linux kernel. It's intended to
+ provide voltage and current control to client or consumer drivers and
+ also provide status information to user space applications through a
+ sysfs interface.
+
+ The intention is to allow systems to dynamically control regulator
+ output in order to save power and prolong battery life. This applies
+ to both voltage regulators (where voltage output is controllable) and
+ current sinks (where current output is controllable).
+
+ This framework safely compiles out if not selected so that client
+ drivers can still be used in systems with no software controllable
+ regulators.
+
+ If unsure, say no.

+ help
+ This driver provides a virtual consumer for the voltage and
+ current regulator API which provides sysfs controls for
+ configuring the supplies requested. This is mainly useful
+ for test purposes.
+
+ If unsure, say no.
