menuconfig REGULATOR bool "Voltage and Current Regulator Support" 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. if REGULATOR config REGULATOR_DEBUG bool "Regulator debug support" help Say yes here to enable debugging support. config REGULATOR_DUMMY bool "Provide a dummy regulator if regulator lookups fail" help 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.
