+         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.

+         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.
