1menuconfig REGULATOR 2 bool "Voltage and Current Regulator Support" 3 help 4 Generic Voltage and Current Regulator support. 5 6 This framework is designed to provide a generic interface to voltage 7 and current regulators within the Linux kernel. It's intended to 8 provide voltage and current control to client or consumer drivers and 9 also provide status information to user space applications through a 10 sysfs interface. 11 12 The intention is to allow systems to dynamically control regulator 13 output in order to save power and prolong battery life. This applies 14 to both voltage regulators (where voltage output is controllable) and 15 current sinks (where current output is controllable). 16 17 This framework safely compiles out if not selected so that client 18 drivers can still be used in systems with no software controllable 19 regulators. 20 21 If unsure, say no. 22 23if REGULATOR 24 25config REGULATOR_DEBUG 26 bool "Regulator debug support" 27 help 28 Say yes here to enable debugging support. 29 30config REGULATOR_FIXED_VOLTAGE 31 tristate "Fixed voltage regulator support" 32 help 33 This driver provides support for fixed voltage regulators, 34 useful for systems which use a combination of software 35 managed regulators and simple non-configurable regulators. 36 37config REGULATOR_VIRTUAL_CONSUMER 38 tristate "Virtual regulator consumer support" 39 help 40 This driver provides a virtual consumer for the voltage and 41 current regulator API which provides sysfs controls for 42 configuring the supplies requested.
