This allows users to enable or disable support for these regulators at build time as they can for other regulators rather than having platforms force the regulators to be built in. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com> Signed-off-by: Liam Girdwood <lrg@slimlogic.co.uk>

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.

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.
