config REGULATOR
bool "Voltage and Current Regulator Support"
default n
help
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.
config REGULATOR_DEBUG
bool "Regulator debug support"
depends on REGULATOR
help
Say yes here to enable debugging support.
config REGULATOR_FIXED_VOLTAGE
tristate
default n
select REGULATOR
config REGULATOR_VIRTUAL_CONSUMER
tristate "Virtual regulator consumer support"
default n
select REGULATOR
help
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.
config REGULATOR_BQ24022
tristate "TI bq24022 Dual Input 1-Cell Li-Ion Charger IC"
default n
select REGULATOR
help
This driver controls a TI bq24022 Charger attached via
GPIOs. The provided current regulator can enable/disable
charging select between 100 mA and 500 mA charging current
limit.
config REGULATOR_WM8400
tristate "Wolfson Microelectroncis WM8400 AudioPlus PMIC"
depends on MFD_WM8400
select REGULATOR
help
This driver provides support for the voltage regulators of the
WM8400 AudioPlus PMIC.
