1Device-Tree bindings for regulators of Active-semi ACT8945A Multi-Function Device 2 3Required properties: 4 - compatible: "active-semi,act8945a", please refer to ../mfd/act8945a.txt. 5 6Optional properties: 7- active-semi,vsel-high: Indicates if the VSEL pin is set to logic-high. 8 If this property is missing, assume the VSEL pin is set to logic-low. 9 10Optional input supply properties: 11 - vp1-supply: The input supply for REG_DCDC1 12 - vp2-supply: The input supply for REG_DCDC2 13 - vp3-supply: The input supply for REG_DCDC3 14 - inl45-supply: The input supply for REG_LDO1 and REG_LDO2 15 - inl67-supply: The input supply for REG_LDO3 and REG_LDO4 16 17Any standard regulator properties can be used to configure the single regulator. 18regulator-initial-mode, regulator-allowed-modes and regulator-mode could be 19specified using mode values from dt-bindings/regulator/active-semi,8945a-regulator.h 20file. 21 22The valid names for regulators are: 23 REG_DCDC1, REG_DCDC2, REG_DCDC3, REG_LDO1, REG_LDO2, REG_LDO3, REG_LDO4. 24 25Example: 26 27#include <dt-bindings/regulator/active-semi,8945a-regulator.h> 28 29 pmic@5b { 30 compatible = "active-semi,act8945a"; 31 reg = <0x5b>; 32 33 active-semi,vsel-high; 34 35 regulators { 36 vdd_1v35_reg: REG_DCDC1 { 37 regulator-name = "VDD_1V35"; 38 regulator-min-microvolt = <1350000>; 39 regulator-max-microvolt = <1350000>; 40 regulator-always-on; 41 42 regulator-allowed-modes = <ACT8945A_REGULATOR_MODE_FIXED>, 43 <ACT8945A_REGULATOR_MODE_LOWPOWER>; 44 regulator-initial-mode = <ACT8945A_REGULATOR_MODE_FIXED>; 45 46 regulator-state-mem { 47 regulator-on-in-suspend; 48 regulator-suspend-min-microvolt=<1400000>; 49 regulator-suspend-max-microvolt=<1400000>; 50 regulator-changeable-in-suspend; 51 regulator-mode=<ACT8945A_REGULATOR_MODE_LOWPOWER>; 52 }; 53 }; 54 55 vdd_1v2_reg: REG_DCDC2 { 56 regulator-name = "VDD_1V2"; 57 regulator-min-microvolt = <1100000>; 58 regulator-max-microvolt = <1300000>; 59 regulator-always-on; 60 61 regulator-allowed-modes = <ACT8945A_REGULATOR_MODE_FIXED>, 62 <ACT8945A_REGULATOR_MODE_LOWPOWER>; 63 regulator-initial-mode = <ACT8945A_REGULATOR_MODE_FIXED>; 64 65 regulator-state-mem { 66 regulator-off-in-suspend; 67 }; 68 }; 69 70 vdd_3v3_reg: REG_DCDC3 { 71 regulator-name = "VDD_3V3"; 72 regulator-min-microvolt = <3300000>; 73 regulator-max-microvolt = <3300000>; 74 regulator-always-on; 75 }; 76 77 vdd_fuse_reg: REG_LDO1 { 78 regulator-name = "VDD_FUSE"; 79 regulator-min-microvolt = <2500000>; 80 regulator-max-microvolt = <2500000>; 81 regulator-always-on; 82 83 regulator-allowed-modes = <ACT8945A_REGULATOR_MODE_NORMAL>, 84 <ACT8945A_REGULATOR_MODE_LOWPOWER>; 85 regulator-initial-mode = <ACT8945A_REGULATOR_MODE_NORMAL>; 86 87 regulator-state-mem { 88 regulator-off-in-suspend; 89 }; 90 }; 91 92 vdd_3v3_lp_reg: REG_LDO2 { 93 regulator-name = "VDD_3V3_LP"; 94 regulator-min-microvolt = <3300000>; 95 regulator-max-microvolt = <3300000>; 96 regulator-always-on; 97 }; 98 99 vdd_led_reg: REG_LDO3 { 100 regulator-name = "VDD_LED"; 101 regulator-min-microvolt = <3300000>; 102 regulator-max-microvolt = <3300000>; 103 regulator-always-on; 104 }; 105 106 vdd_sdhc_1v8_reg: REG_LDO4 { 107 regulator-name = "VDD_SDHC_1V8"; 108 regulator-min-microvolt = <1800000>; 109 regulator-max-microvolt = <1800000>; 110 regulator-always-on; 111 }; 112 }; 113 };
