1menuconfig REGULATOR
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.
20
21	  If unsure, say no.

35	  constraints then the regulator core will provide an always
36	  enabled dummy regulator will be provided, allowing consumer
37	  drivers to continue.
