2 bool "Voltage and Current Regulator Support"
3 help
4 Generic Voltage and Current Regulator support.
5
6 This framework is designed to provide a generic interface to voltage
7 and current regulators within the Linux kernel. It's intended to
8 provide voltage and current control to client or consumer drivers and
9 also provide status information to user space applications through a
10 sysfs interface.
11
12 The intention is to allow systems to dynamically control regulator
13 output in order to save power and prolong battery life. This applies
14 to both voltage regulators (where voltage output is controllable) and
15 current sinks (where current output is controllable).
16
17 This framework safely compiles out if not selected so that client
18 drivers can still be used in systems with no software controllable
19 regulators.

21 If unsure, say no.
