1menuconfig REGULATOR 2 bool "Voltage and Current Regulator Support" 3 default n 4 help 5 Generic Voltage and Current Regulator support. 6 7 This framework is designed to provide a generic interface to voltage 8 and current regulators within the Linux kernel. It's intended to 9 provide voltage and current control to client or consumer drivers and 10 also provide status information to user space applications through a 11 sysfs interface. 12 13 The intention is to allow systems to dynamically control regulator 14 output in order to save power and prolong battery life. This applies 15 to both voltage regulators (where voltage output is controllable) and 16 current sinks (where current output is controllable). 17 18 This framework safely compiles out if not selected so that client 19 drivers can still be used in systems with no software controllable 20 regulators. 21 22 If unsure, say no. 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 33 default n 34 35config REGULATOR_VIRTUAL_CONSUMER 36 tristate "Virtual regulator consumer support" 37 default n 38 help 39 This driver provides a virtual consumer for the voltage and 40 current regulator API which provides sysfs controls for 41 configuring the supplies requested. This is mainly useful 42 for test purposes. 43 44 If unsure, say no. 45 46config REGULATOR_BQ24022 47 tristate "TI bq24022 Dual Input 1-Cell Li-Ion Charger IC" 48 default n 49 help 50 This driver controls a TI bq24022 Charger attached via 51 GPIOs.
