+          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.

+config REGULATOR_DEBUG

+        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.
