1ACT88xx regulators 2------------------- 3 4Required properties: 5- compatible: "active-semi,act8846" or "active-semi,act8865" or "active-semi,act8600" 6- reg: I2C slave address 7 8Optional properties: 9- system-power-controller: Telling whether or not this pmic is controlling 10 the system power. See Documentation/devicetree/bindings/power/power-controller.txt . 11- active-semi,vsel-high: Indicates the VSEL pin is high. 12 If this property is missing, assume the VSEL pin is low(0). 13 14Optional input supply properties: 15- for act8600: 16 - vp1-supply: The input supply for DCDC_REG1 17 - vp2-supply: The input supply for DCDC_REG2 18 - vp3-supply: The input supply for DCDC_REG3 19 - inl-supply: The input supply for LDO_REG5, LDO_REG6, LDO_REG7 and LDO_REG8 20 SUDCDC_REG4, LDO_REG9 and LDO_REG10 do not have separate supplies. 21- for act8846: 22 - vp1-supply: The input supply for REG1 23 - vp2-supply: The input supply for REG2 24 - vp3-supply: The input supply for REG3 25 - vp4-supply: The input supply for REG4 26 - inl1-supply: The input supply for REG5, REG6 and REG7 27 - inl2-supply: The input supply for REG8 and LDO_REG9 28 - inl3-supply: The input supply for REG10, REG11 and REG12 29- for act8865: 30 - vp1-supply: The input supply for DCDC_REG1 31 - vp2-supply: The input supply for DCDC_REG2 32 - vp3-supply: The input supply for DCDC_REG3 33 - inl45-supply: The input supply for LDO_REG1 and LDO_REG2 34 - inl67-supply: The input supply for LDO_REG3 and LDO_REG4 35 36Any standard regulator properties can be used to configure the single regulator. 37regulator-initial-mode, regulator-allowed-modes and regulator-mode could be specified 38for act8865 using mode values from dt-bindings/regulator/active-semi,8865-regulator.h 39file. 40 41The valid names for regulators are: 42 - for act8846: 43 REG1, REG2, REG3, REG4, REG5, REG6, REG7, REG8, REG9, REG10, REG11, REG12 44 - for act8865: 45 DCDC_REG1, DCDC_REG2, DCDC_REG3, LDO_REG1, LDO_REG2, LDO_REG3, LDO_REG4. 46 - for act8600: 47 DCDC_REG1, DCDC_REG2, DCDC_REG3, SUDCDC_REG4, LDO_REG5, LDO_REG6, LDO_REG7, 48 LDO_REG8, LDO_REG9, LDO_REG10, 49 50Example: 51-------- 52 53#include <dt-bindings/regulator/active-semi,8865-regulator.h> 54 55 i2c1: i2c@f0018000 { 56 pmic: act8865@5b { 57 compatible = "active-semi,act8865"; 58 reg = <0x5b>; 59 active-semi,vsel-high; 60 61 regulators { 62 vcc_1v8_reg: DCDC_REG1 { 63 regulator-name = "VCC_1V8"; 64 regulator-min-microvolt = <1800000>; 65 regulator-max-microvolt = <1800000>; 66 regulator-always-on; 67 }; 68 69 vcc_1v2_reg: DCDC_REG2 { 70 regulator-name = "VCC_1V2"; 71 regulator-min-microvolt = <1100000>; 72 regulator-max-microvolt = <1300000>; 73 regulator-always-on; 74 75 regulator-allowed-modes = <ACT8865_REGULATOR_MODE_FIXED>, 76 <ACT8865_REGULATOR_MODE_LOWPOWER>; 77 regulator-initial-mode = <ACT8865_REGULATOR_MODE_FIXED>; 78 79 regulator-state-mem { 80 regulator-on-in-suspend; 81 regulator-suspend-min-microvolt = <1150000>; 82 regulator-suspend-max-microvolt = <1150000>; 83 regulator-changeable-in-suspend; 84 regulator-mode = <ACT8865_REGULATOR_MODE_LOWPOWER>; 85 }; 86 }; 87 88 vcc_3v3_reg: DCDC_REG3 { 89 regulator-name = "VCC_3V3"; 90 regulator-min-microvolt = <3300000>; 91 regulator-max-microvolt = <3300000>; 92 regulator-always-on; 93 }; 94 95 vddana_reg: LDO_REG1 { 96 regulator-name = "VDDANA"; 97 regulator-min-microvolt = <3300000>; 98 regulator-max-microvolt = <3300000>; 99 regulator-always-on; 100 101 regulator-allowed-modes = <ACT8865_REGULATOR_MODE_NORMAL>, 102 <ACT8865_REGULATOR_MODE_LOWPOWER>; 103 regulator-initial-mode = <ACT8865_REGULATOR_MODE_NORMAL>; 104 105 regulator-state-mem { 106 regulator-off-in-suspend; 107 }; 108 }; 109 110 vddfuse_reg: LDO_REG2 { 111 regulator-name = "FUSE_2V5"; 112 regulator-min-microvolt = <2500000>; 113 regulator-max-microvolt = <2500000>; 114 }; 115 }; 116 }; 117 };
