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 23 24if REGULATOR 25 26config REGULATOR_DEBUG 27 bool "Regulator debug support" 28 help 29 Say yes here to enable debugging support. 30 31config REGULATOR_DUMMY 32 bool "Provide a dummy regulator if regulator lookups fail" 33 help 34 If this option is enabled then when a regulator lookup fails 35 and the board has not specified that it has provided full 36 constraints the regulator core will provide an always 37 enabled dummy regulator, allowing consumer drivers to continue. 38 39 A warning will be generated when this substitution is done. 40 41config REGULATOR_FIXED_VOLTAGE 42 tristate "Fixed voltage regulator support" 43 help 44 This driver provides support for fixed voltage regulators, 45 useful for systems which use a combination of software 46 managed regulators and simple non-configurable regulators. 47 48config REGULATOR_VIRTUAL_CONSUMER 49 tristate "Virtual regulator consumer support" 50 help 51 This driver provides a virtual consumer for the voltage and 52 current regulator API which provides sysfs controls for 53 configuring the supplies requested.
