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 then the regulator core will provide an always

enabled dummy regulator will be provided, allowing consumer

|
|

|
drivers to continue.

A warning will be generated when this substitution is done.

regulator: twl4030 regulators
Support most of the LDO regulators in the twl4030 family chips.
In the case of LDOs supporting MMC/SD, the voltage controls are
used; but in most other cases, the regulator framework is only
used to enable/disable a supplies, conserving power when a given
voltage rail is not needed.
The drivers/mfd/twl4030-core.c code already sets up the various
regulators according to board-specific configuration, and knows
that some chips don't provide the full set of voltage rails.
The omitted regulators are intended to be under hardware control,
such as during the hardware-mediated system powerup, powerdown,
and suspend states. Unless/until software hooks are known to
be safe, they won't be exported here.
These regulators implement the new get_status() operation, but
can't realistically implement get_mode(); the status output is
effectively the result of a vote, with the relevant hardware
inputs not exposed.
