1menu "Voltage and Current regulators" 2 3config REGULATOR 4 bool "Voltage and Current Regulator Support" 5 default n 6 help 7 Generic Voltage and Current Regulator support. 8 9 This framework is designed to provide a generic interface to voltage 10 and current regulators within the Linux kernel. It's intended to 11 provide voltage and current control to client or consumer drivers and 12 also provide status information to user space applications through a 13 sysfs interface. 14 15 The intention is to allow systems to dynamically control regulator 16 output in order to save power and prolong battery life. This applies 17 to both voltage regulators (where voltage output is controllable) and 18 current sinks (where current output is controllable). 19 20 This framework safely compiles out if not selected so that client 21 drivers can still be used in systems with no software controllable 22 regulators. 23 24 If unsure, say no. 25 26config REGULATOR_DEBUG 27 bool "Regulator debug support" 28 depends on REGULATOR 29 help 30 Say yes here to enable debugging support. 31 32config REGULATOR_FIXED_VOLTAGE 33 tristate 34 default n 35 select REGULATOR 36 37config REGULATOR_VIRTUAL_CONSUMER 38 tristate "Virtual regulator consumer support" 39 default n 40 select REGULATOR 41 help 42 This driver provides a virtual consumer for the voltage and 43 current regulator API which provides sysfs controls for 44 configuring the supplies requested. This is mainly useful 45 for test purposes. 46 47 If unsure, say no. 48 49config REGULATOR_BQ24022 50 tristate "TI bq24022 Dual Input 1-Cell Li-Ion Charger IC" 51 default n 52 select REGULATOR 53 help 54 This driver controls a TI bq24022 Charger attached via 55 GPIOs. The provided current regulator can enable/disable 56 charging select between 100 mA and 500 mA charging current 57 limit. 58 59config REGULATOR_WM8350 60 tristate "Wolfson Microelectroncis WM8350 AudioPlus PMIC" 61 depends on MFD_WM8350 62 select REGULATOR 63 help 64 This driver provides support for the voltage and current regulators 65 of the WM8350 AudioPlus PMIC. 66 67config REGULATOR_WM8400 68 tristate "Wolfson Microelectroncis WM8400 AudioPlus PMIC" 69 depends on MFD_WM8400 70 select REGULATOR 71 help 72 This driver provides support for the voltage regulators of the 73 WM8400 AudioPlus PMIC. 74 75config REGULATOR_DA903X 76 tristate "Support regulators on Dialog Semiconductor DA9030/DA9034 PMIC" 77 depends on PMIC_DA903X 78 select REGULATOR 79 help 80 Say y here to support the BUCKs and LDOs regulators found on 81 Dialog Semiconductor DA9030/DA9034 PMIC. 82 83endmenu 84
