|
|
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.

If this option is enabled then when a regulator lookup fails

and the board has not specified that it has provided full
|
|
constraints the regulator core will provide an always
|
|
enabled dummy regulator, allowing consumer drivers to continue.

A warning will be generated when this substitution is done.

|
is regulated down by an integrated LDO, providing a positive supply
|
|
rail. It also has a negative supply rail which is generated by an
|
|
integrated negative charge pump driven from the boost converter
|
|
output. Both output regulators support 4V~6V voltage range and
|
|
can be configured separately. Each regulator can be enabled and
|
|
disabled independently through an external pin.

tristate "Stub Regulator"
|
|
help
|
|
This driver adds stub regulator support. The driver is absent of any
|
|
real hardware based implementation. It allows for clients to register
|
|
their regulator device constraints and use all of the standard
|
|
regulator interfaces. This is useful for bringing up new platforms
|
|
when the real hardware based implementation may not be yet available.
|
|
Clients can use the real regulator device names with proper
|
|
constraint checking while the real driver is being developed.
