It's intended to 10 provide voltage and current control to client or consumer drivers and 11 also provide status information to user space applications through a 12 sysfs interface. 13 14 The intention is to allow systems to dynamically control regulator 15 output in order to save power and prolong battery life. This applies 16 to both voltage regulators (where voltage output is controllable) and 17 current sinks (where current output is controllable). 18 19 This framework safely compiles out if not selected so that client 20 drivers can still be used in systems with no software controllable 21 regulators. 22 23 If unsure, say no. 24 25 26if REGULATOR 27 28config REGULATOR_DEBUG 29 bool "Regulator debug support" 30 help 31 Say yes here to enable debugging support. 32 33config REGULATOR_FIXED_VOLTAGE 34 tristate "Fixed voltage regulator support" 35 help 36 This driver provides support for fixed voltage regulators, 37 useful for systems which use a combination of software 38 managed regulators and simple non-configurable regulators. 39 40config REGULATOR_VIRTUAL_CONSUMER 41 tristate "Virtual regulator consumer support" 42 help 43 This driver provides a virtual consumer for the voltage and 44 current regulator API which provides sysfs controls for 45 configuring the supplies requested.
