EN in which case it functions as an enable pin. 46 2. VSENSE which compares the voltages and triggers an automatic 47 on/off request. 48 3. PB in which case it can be configured to trigger an interrupt 49 to the SoC. 50 ti,power-button reflects the last one of those options 51 where the board has a button wired to the pin and triggers 52 an interrupt on pressing it. 53 54 regulators: 55 type: object 56 description: | 57 list of regulators provided by this controller 58 59 patternProperties: 60 "^ldo[1-4]$": 61 type: object 62 $ref: regulator.yaml# 63 description: 64 Properties for single LDO regulator. 65 66 unevaluatedProperties: false 67 68 "^buck[1-3]$": 69 type: object 70 $ref: regulator.yaml# 71 description: 72 Properties for single BUCK regulator. 73 74 unevaluatedProperties: false 75 76 additionalProperties: false 77 78patternProperties: 79 "^buck[1-3]-supply$": 80 description: Input supply phandle of one regulator. 81 82 "^ldo[1-4]-supply$": 83 description: Input supply phandle of one regulator. 84 85required: 86 - compatible 87 - reg 88 - interrupts 89 - regulators 90 91additionalProperties: false 92 93examples: 94 - | 95 #include <dt-bindings/interrupt-controller/arm-gic.h> 96 i2c { 97 #address-cells = <1>; 98 #size-cells = <0>; 99 100 tps65219: pmic@30 { 101 compatible = "ti,tps65219"; 102 reg = <0x30>; 103 buck1-supply = <&vcc_3v3_sys>; 104 buck2-supply = <&vcc_3v3_sys>; 105 buck3-supply = <&vcc_3v3_sys>; 106 ldo1-supply = <&vcc_3v3_sys>; 107 ldo2-supply = <&buck2_reg>; 108 ldo3-supply = <&vcc_3v3_sys>; 109 ldo4-supply = <&vcc_3v3_sys>; 110 111 pinctrl-0 = <&pmic_irq_pins_default>; 112 113 interrupt-parent = <&gic500>; 114 interrupts = <GIC_SPI 224 IRQ_TYPE_LEVEL_HIGH>; 115 ti,power-button; 116 117 regulators { 118 buck1_reg: buck1 { 119 regulator-name = "VDD_CORE"; 120 regulator-min-microvolt = <750000>; 121 regulator-max-microvolt = <750000>; 122 regulator-boot-on; 123 regulator-always-on; 124 }; 125 126 buck2_reg: buck2 { 127 regulator-name = "VCC1V8"; 128 regulator-min-microvolt = <1800000>; 129 regulator-max-microvolt = <1800000>; 130 regulator-boot-on; 131 regulator-always-on; 132 }; 133 134 buck3_reg: buck3 { 135 regulator-name = "VDD_LPDDR4"; 136 regulator-min-microvolt = <1100000>; 137 regulator-max-microvolt = <1100000>; 138 regulator-boot-on; 139 regulator-always-on; 140 }; 141 142 ldo1_reg: ldo1 { 143 regulator-name = "VDDSHV_SD_IO_PMIC"; 144 regulator-min-microvolt = <33000000>; 145 regulator-max-microvolt = <33000000>; 146 }; 147 148 ldo2_reg: ldo2 { 149 regulator-name = "VDDAR_CORE"; 150 regulator-min-microvolt = <850000>; 151 regulator-max-microvolt = <850000>; 152 regulator-boot-on; 153 regulator-always-on; 154 }; 155 156 ldo3_reg: ldo3 { 157 regulator-name = "VDDA_1V8"; 158 regulator-min-microvolt = <18000000>; 159 regulator-max-microvolt = <18000000>; 160 regulator-boot-on; 161 regulator-always-on; 162 }; 163 164 ldo4_reg: ldo4 { 165 regulator-name = "VDD_PHY_2V5"; 166 regulator-min-microvolt = <25000000>; 167 regulator-max-microvolt = <25000000>; 168 regulator-boot-on; 169 regulator-always-on; 170 }; 171 }; 172 }; 173 }; 174
