1TPS6507x Power Management Integrated Circuit 2 3Required properties: 4- compatible: "ti,tps6507x" 5- reg: I2C slave address 6- regulators: This is the list of child nodes that specify the regulator 7 initialization data for defined regulators. Not all regulators for the 8 given device need to be present. The definition for each of these nodes 9 is defined using the standard binding for regulators found at 10 Documentation/devicetree/bindings/regulator/regulator.txt. 11 The regulator is matched with the regulator-compatible. 12 13 The valid regulator-compatible values are: 14 tps6507x: vdcdc1, vdcdc2, vdcdc3, vldo1, vldo2 15- xxx-supply: Input voltage supply regulator. 16 These entries are required if regulators are enabled for a device. 17 Missing of these properties can cause the regulator registration 18 fails. 19 If some of input supply is powered through battery or always-on 20 supply then also it is require to have these parameters with proper 21 node handle of always on power supply. 22 tps6507x: 23 vindcdc1_2-supply: VDCDC1 and VDCDC2 input. 24 vindcdc3-supply : VDCDC3 input. 25 vldo1_2-supply : VLDO1 and VLDO2 input. 26 27Regulator Optional properties: 28- defdcdc_default: It's property of DCDC2 and DCDC3 regulators. 29 0: If defdcdc pin of DCDC2/DCDC3 is pulled to GND. 30 1: If defdcdc pin of DCDC2/DCDC3 is driven HIGH. 31 If this property is not defined, it defaults to 0 (not enabled). 32 33Example: 34 35 pmu: tps6507x@48 { 36 compatible = "ti,tps6507x"; 37 reg = <0x48>; 38 39 vindcdc1_2-supply = <&vbat>; 40 vindcdc3-supply = <...>; 41 vinldo1_2-supply = <...>; 42 43 regulators { 44 #address-cells = <1>; 45 #size-cells = <0>; 46 47 vdcdc1_reg: regulator@0 { 48 regulator-compatible = "VDCDC1"; 49 reg = <0>; 50 regulator-min-microvolt = <3150000>; 51 regulator-max-microvolt = <3450000>; 52 regulator-always-on; 53 regulator-boot-on; 54 }; 55 vdcdc2_reg: regulator@1 { 56 regulator-compatible = "VDCDC2"; 57 reg = <1>; 58 regulator-min-microvolt = <1710000>; 59 regulator-max-microvolt = <3450000>; 60 regulator-always-on; 61 regulator-boot-on; 62 defdcdc_default = <1>; 63 }; 64 vdcdc3_reg: regulator@2 { 65 regulator-compatible = "VDCDC3"; 66 reg = <2>; 67 regulator-min-microvolt = <950000> 68 regulator-max-microvolt = <1350000>; 69 regulator-always-on; 70 regulator-boot-on; 71 defdcdc_default = <1>; 72 }; 73 ldo1_reg: regulator@3 { 74 regulator-compatible = "LDO1"; 75 reg = <3>; 76 regulator-min-microvolt = <1710000>; 77 regulator-max-microvolt = <1890000>; 78 regulator-always-on; 79 regulator-boot-on; 80 }; 81 ldo2_reg: regulator@4 { 82 regulator-compatible = "LDO2"; 83 reg = <4>; 84 regulator-min-microvolt = <1140000>; 85 regulator-max-microvolt = <1320000>; 86 regulator-always-on; 87 regulator-boot-on; 88 }; 89 }; 90 91 }; 92
