menuconfig REGULATOR bool "Voltage and Current Regulator Support" default n help Generic Voltage and Current Regulator support. This framework is designed to provide a generic interface to voltage and current regulators within the Linux kernel. It's intended to provide voltage and current control to client or consumer drivers and also provide status information to user space applications through a sysfs interface. The intention is to allow systems to dynamically control regulator output in order to save power and prolong battery life. This applies to both voltage regulators (where voltage output is controllable) and current sinks (where current output is controllable). This framework safely compiles out if not selected so that client drivers can still be used in systems with no software controllable regulators. If unsure, say no. if REGULATOR config REGULATOR_DEBUG bool "Regulator debug support" help Say yes here to enable debugging support. config REGULATOR_FIXED_VOLTAGE tristate "Fixed voltage regulator support" default n help This driver provides support for fixed voltage regulators, useful for systems which use a combination of software managed regulators and simple non-configurable regulators. config REGULATOR_VIRTUAL_CONSUMER tristate "Virtual regulator consumer support" default n help This driver provides a virtual consumer for the voltage and current regulator API which provides sysfs controls for configuring the supplies requested. This is mainly useful for test purposes. If unsure, say no. config REGULATOR_USERSPACE_CONSUMER tristate "Userspace regulator consumer support" default n help There are some classes of devices that are controlled entirely from user space. Usersapce consumer driver provides ability to control power supplies for such devices. If unsure, say no. config REGULATOR_BQ24022 tristate "TI bq24022 Dual Input 1-Cell Li-Ion Charger IC" default n help This driver controls a TI bq24022 Charger attached via GPIOs. The provided current regulator can enable/disable charging select between 100 mA and 500 mA charging current limit. config REGULATOR_MAX1586 tristate "Maxim 1586/1587 voltage regulator" depends on I2C default n help This driver controls a Maxim 1586 or 1587 voltage output regulator via I2C bus. The provided regulator is suitable for PXA27x chips to control VCC_CORE and VCC_USIM voltages. config REGULATOR_TWL4030 bool "TI TWL4030/TWL5030/TPS695x0 PMIC" depends on TWL4030_CORE help This driver supports the voltage regulators provided by this family of companion chips. config REGULATOR_WM8350 tristate "Wolfson Microelectroncis WM8350 AudioPlus PMIC" depends on MFD_WM8350 help This driver provides support for the voltage and current regulators of the WM8350 AudioPlus PMIC. config REGULATOR_WM8400 tristate "Wolfson Microelectroncis WM8400 AudioPlus PMIC" depends on MFD_WM8400 help This driver provides support for the voltage regulators of the WM8400 AudioPlus PMIC. config REGULATOR_DA903X tristate "Support regulators on Dialog Semiconductor DA9030/DA9034 PMIC" depends on PMIC_DA903X help Say y here to support the BUCKs and LDOs regulators found on Dialog Semiconductor DA9030/DA9034 PMIC. config REGULATOR_PCF50633 tristate "PCF50633 regulator driver" depends on MFD_PCF50633 help Say Y here to support the voltage regulators and convertors on PCF50633 config REGULATOR_LP3971 tristate "National Semiconductors LP3971 PMIC regulator driver" depends on I2C help Say Y here to support the voltage regulators and convertors on National Semiconductors LP3971 PMIC config REGULATOR_PCAP tristate "PCAP2 regulator driver" depends on EZX_PCAP help This driver provides support for the voltage regulators of the PCAP2 PMIC. endif
