The WM8350 features six DCDC convertors (four buck and two boost), four LDO voltage regulators and two constant current sinks. This driver adds support for these through the regulator API. This driver was written by Liam Girdwood with updates for submission from Mark Brown.

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.

If unsure, say no.
