Regulators - not used but preferred to be managed by the OS should be - listed as well. - See Documentation/devicetree/bindings/regulator/regulator.txt - for more information on standard regulator bindings. - -Optional properties for DCDC regulators: -- x-powers,dcdc-workmode: 1 for PWM mode, 0 for AUTO (PWM/PFM) mode - Default: Current hardware setting - The DCDC regulators work in a mixed PWM/PFM mode, - using PFM under light loads and switching to PWM - for heavier loads. Forcing PWM mode trades efficiency - under light loads for lower output noise. This - probably makes sense for HiFi audio related - applications that aren't battery constrained. - -AXP202/AXP209 regulators, type, and corresponding input supply names: - -Regulator Type Supply Name Notes ---------- ---- ----------- ----- -DCDC2 : DC-DC buck : vin2-supply -DCDC3 : DC-DC buck : vin3-supply -LDO1 : LDO : acin-supply : always on -LDO2 : LDO : ldo24in-supply : shared supply -LDO3 : LDO : ldo3in-supply -LDO4 : LDO : ldo24in-supply : shared supply -LDO5 : LDO : ldo5in-supply - -AXP221/AXP223 regulators, type, and corresponding input supply names: - -Regulator Type Supply Name Notes ---------- ---- ----------- ----- -DCDC1 : DC-DC buck : vin1-supply -DCDC2 : DC-DC buck : vin2-supply -DCDC3 : DC-DC buck : vin3-supply -DCDC4 : DC-DC buck : vin4-supply -DCDC5 : DC-DC buck : vin5-supply -DC1SW : On/Off Switch : : DCDC1 secondary output -DC5LDO : LDO : : input from DCDC5 -ALDO1 : LDO : aldoin-supply : shared supply -ALDO2 : LDO : aldoin-supply : shared supply -ALDO3 : LDO : aldoin-supply : shared supply -DLDO1 : LDO : dldoin-supply : shared supply -DLDO2 : LDO : dldoin-supply : shared supply -DLDO3 : LDO : dldoin-supply : shared supply -DLDO4 : LDO : dldoin-supply : shared supply -ELDO1 : LDO : eldoin-supply : shared supply -ELDO2 : LDO : eldoin-supply : shared supply -ELDO3 : LDO : eldoin-supply : shared supply -LDO_IO0 : LDO : ips-supply : GPIO 0 -LDO_IO1 : LDO : ips-supply : GPIO 1 -RTC_LDO : LDO : ips-supply : always on -DRIVEVBUS : Enable output : drivevbus-supply : external regulator - -AXP803 regulators, type, and corresponding input supply names: - -Regulator Type Supply Name Notes ---------- ---- ----------- ----- -DCDC1 : DC-DC buck : vin1-supply -DCDC2 : DC-DC buck : vin2-supply : poly-phase capable -DCDC3 : DC-DC buck : vin3-supply : poly-phase capable -DCDC4 : DC-DC buck : vin4-supply -DCDC5 : DC-DC buck : vin5-supply : poly-phase capable -DCDC6 : DC-DC buck : vin6-supply : poly-phase capable -DC1SW : On/Off Switch : : DCDC1 secondary output -ALDO1 : LDO : aldoin-supply : shared supply -ALDO2 : LDO : aldoin-supply : shared supply -ALDO3 : LDO : aldoin-supply : shared supply -DLDO1 : LDO : dldoin-supply : shared supply -DLDO2 : LDO : dldoin-supply : shared supply -DLDO3 : LDO : dldoin-supply : shared supply -DLDO4 : LDO : dldoin-supply : shared supply -ELDO1 : LDO : eldoin-supply : shared supply -ELDO2 : LDO : eldoin-supply : shared supply -ELDO3 : LDO : eldoin-supply : shared supply -FLDO1 : LDO : fldoin-supply : shared supply -FLDO2 : LDO : fldoin-supply : shared supply -LDO_IO0 : LDO : ips-supply : GPIO 0 -LDO_IO1 : LDO : ips-supply : GPIO 1 -RTC_LDO : LDO : ips-supply : always on -DRIVEVBUS : Enable output : drivevbus-supply : external regulator - -AXP806 regulators, type, and corresponding input supply names: - -Regulator Type Supply Name Notes ---------- ---- ----------- ----- -DCDCA : DC-DC buck : vina-supply : poly-phase capable -DCDCB : DC-DC buck : vinb-supply : poly-phase capable -DCDCC : DC-DC buck : vinc-supply : poly-phase capable -DCDCD : DC-DC buck : vind-supply : poly-phase capable -DCDCE : DC-DC buck : vine-supply : poly-phase capable -ALDO1 : LDO : aldoin-supply : shared supply -ALDO2 : LDO : aldoin-supply : shared supply -ALDO3 : LDO : aldoin-supply : shared supply -BLDO1 : LDO : bldoin-supply : shared supply -BLDO2 : LDO : bldoin-supply : shared supply -BLDO3 : LDO : bldoin-supply : shared supply -BLDO4 : LDO : bldoin-supply : shared supply -CLDO1 : LDO : cldoin-supply : shared supply -CLDO2 : LDO : cldoin-supply : shared supply -CLDO3 : LDO : cldoin-supply : shared supply -SW : On/Off Switch : swin-supply - -Additionally, the AXP806 DC-DC regulators support poly-phase arrangements -for higher output current.
