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_FIXED_VOLTAGE 32 tristate "Fixed voltage regulator support" 33 help 34 This driver provides support for fixed voltage regulators, 35 useful for systems which use a combination of software 36 managed regulators and simple non-configurable regulators. 37 38config REGULATOR_VIRTUAL_CONSUMER 39 tristate "Virtual regulator consumer support" 40 help 41 This driver provides a virtual consumer for the voltage and 42 current regulator API which provides sysfs controls for 43 configuring the supplies requested.
