7 Generic Voltage and Current Regulator support.
8
9 This framework is designed to provide a generic interface to voltage
10 and current regulators within the Linux kernel. It's intended to
11 provide voltage and current control to client or consumer drivers and
12 also provide status information to user space applications through a
13 sysfs interface.
14
15 The intention is to allow systems to dynamically control regulator
16 output in order to save power and prolong battery life. This applies
17 to both voltage regulators (where voltage output is controllable) and
18 current sinks (where current output is controllable).
19
20 This framework safely compiles out if not selected so that client
21 drivers can still be used in systems with no software controllable
22 regulators.

24 If unsure, say no.

42 This driver provides a virtual consumer for the voltage and
43 current regulator API which provides sysfs controls for
44 configuring the supplies requested. This is mainly useful
45 for test purposes.
