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.
