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.
Say yes here to enable debugging support.
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.
This driver provides support for fixed voltage regulators, useful for systems which use a combination of software managed regulators and simple non-configurable regulators.
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.
There are some classes of devices that are controlled entirely from user space. Userspace consumer driver provides ability to control power supplies for such devices. If unsure, say no.
