1TPS65910 Power Management Integrated Circuit 2 3Required properties: 4- compatible: "ti,tps65910" or "ti,tps65911" 5- reg: I2C slave address 6- interrupts: the interrupt outputs of the controller 7- #gpio-cells: number of cells to describe a GPIO, this should be 2. 8 The first cell is the GPIO number. 9 The second cell is used to specify additional options <unused>. 10- gpio-controller: mark the device as a GPIO controller 11- #interrupt-cells: the number of cells to describe an IRQ, this should be 2. 12 The first cell is the IRQ number. 13 The second cell is the flags, encoded as the trigger masks from 14 Documentation/devicetree/bindings/interrupts.txt 15- regulators: This is the list of child nodes that specify the regulator 16 initialization data for defined regulators. Not all regulators for the given 17 device need to be present. The definition for each of these nodes is defined 18 using the standard binding for regulators found at 19 Documentation/devicetree/bindings/regulator/regulator.txt. 20 The regulator is matched with the regulator-compatible. 21 22 The valid regulator-compatible values are: 23 tps65910: vrtc, vio, vdd1, vdd2, vdd3, vdig1, vdig2, vpll, vdac, vaux1, 24 vaux2, vaux33, vmmc 25 tps65911: vrtc, vio, vdd1, vdd3, vddctrl, ldo1, ldo2, ldo3, ldo4, ldo5, 26 ldo6, ldo7, ldo8 27 28- xxx-supply: Input voltage supply regulator. 29 These entries are require if regulators are enabled for a device. Missing of these 30 properties can cause the regulator registration fails. 31 If some of input supply is powered through battery or always-on supply then 32 also it is require to have these parameters with proper node handle of always 33 on power supply. 34 tps65910: 35 vcc1-supply: VDD1 input. 36 vcc2-supply: VDD2 input. 37 vcc3-supply: VAUX33 and VMMC input. 38 vcc4-supply: VAUX1 and VAUX2 input. 39 vcc5-supply: VPLL and VDAC input. 40 vcc6-supply: VDIG1 and VDIG2 input. 41 vcc7-supply: VRTC input. 42 vccio-supply: VIO input. 43 tps65911: 44 vcc1-supply: VDD1 input. 45 vcc2-supply: VDD2 input. 46 vcc3-supply: LDO6, LDO7 and LDO8 input. 47 vcc4-supply: LDO5 input. 48 vcc5-supply: LDO3 and LDO4 input. 49 vcc6-supply: LDO1 and LDO2 input. 50 vcc7-supply: VRTC input. 51 vccio-supply: VIO input. 52 53Optional properties: 54- ti,vmbch-threshold: (tps65911) main battery charged threshold 55 comparator.

(see VMBCH_VSEL in TPS65910 datasheet) 58- ti,en-ck32k-xtal: enable external 32-kHz crystal oscillator (see CK32K_CTRL 59 in TPS6591X datasheet) 60- ti,en-gpio-sleep: enable sleep control for gpios 61 There should be 9 entries here, one for each gpio. 62- ti,system-power-controller: Telling whether or not this pmic is controlling 63 the system power. 64 65Regulator Optional properties: 66- ti,regulator-ext-sleep-control: enable external sleep 67 control through external inputs [0 (not enabled), 1 (EN1), 2 (EN2) or 4(EN3)] 68 If this property is not defined, it defaults to 0 (not enabled). 69 70Example: 71 72 pmu: tps65910@d2 { 73 compatible = "ti,tps65910"; 74 reg = <0xd2>; 75 interrupt-parent = <&intc>; 76 interrupts = < 0 118 0x04 >; 77 78 #gpio-cells = <2>; 79 gpio-controller; 80 81 #interrupt-cells = <2>; 82 interrupt-controller; 83 84 ti,system-power-controller; 85 86 ti,vmbch-threshold = 0; 87 ti,vmbch2-threshold = 0; 88 ti,en-ck32k-xtal; 89 ti,en-gpio-sleep = <0 0 1 0 0 0 0 0 0>; 90 91 vcc1-supply = <®_parent>; 92 vcc2-supply = <&some_reg>; 93 vcc3-supply = <...>; 94 vcc4-supply = <...>; 95 vcc5-supply = <...>; 96 vcc6-supply = <...>; 97 vcc7-supply = <...>; 98 vccio-supply = <...>; 99 100 regulators { 101 #address-cells = <1>; 102 #size-cells = <0>; 103 104 vdd1_reg: regulator@0 { 105 regulator-compatible = "vdd1"; 106 reg = <0>; 107 regulator-min-microvolt = < 600000>; 108 regulator-max-microvolt = <1500000>; 109 regulator-always-on; 110 regulator-boot-on; 111 ti,regulator-ext-sleep-control = <0>; 112 }; 113 vdd2_reg: regulator@1 { 114 regulator-compatible = "vdd2"; 115 reg = <1>; 116 regulator-min-microvolt = < 600000>; 117 regulator-max-microvolt = <1500000>; 118 regulator-always-on; 119 regulator-boot-on; 120 ti,regulator-ext-sleep-control = <4>; 121 }; 122 vddctrl_reg: regulator@2 { 123 regulator-compatible = "vddctrl"; 124 reg = <2>; 125 regulator-min-microvolt = < 600000>; 126 regulator-max-microvolt = <1400000>; 127 regulator-always-on; 128 regulator-boot-on; 129 ti,regulator-ext-sleep-control = <0>; 130 }; 131 vio_reg: regulator@3 { 132 regulator-compatible = "vio"; 133 reg = <3>; 134 regulator-min-microvolt = <1500000>; 135 regulator-max-microvolt = <1800000>; 136 regulator-always-on; 137 regulator-boot-on; 138 ti,regulator-ext-sleep-control = <1>; 139 }; 140 ldo1_reg: regulator@4 { 141 regulator-compatible = "ldo1"; 142 reg = <4>; 143 regulator-min-microvolt = <1000000>; 144 regulator-max-microvolt = <3300000>; 145 ti,regulator-ext-sleep-control = <0>; 146 }; 147 ldo2_reg: regulator@5 { 148 regulator-compatible = "ldo2"; 149 reg = <5>; 150 regulator-min-microvolt = <1050000>; 151 regulator-max-microvolt = <1050000>; 152 ti,regulator-ext-sleep-control = <0>; 153 }; 154 ldo3_reg: regulator@6 { 155 regulator-compatible = "ldo3"; 156 reg = <6>; 157 regulator-min-microvolt = <1000000>; 158 regulator-max-microvolt = <3300000>; 159 ti,regulator-ext-sleep-control = <0>; 160 }; 161 ldo4_reg: regulator@7 { 162 regulator-compatible = "ldo4"; 163 reg = <7>; 164 regulator-min-microvolt = <1000000>; 165 regulator-max-microvolt = <3300000>; 166 regulator-always-on; 167 ti,regulator-ext-sleep-control = <0>; 168 }; 169 ldo5_reg: regulator@8 { 170 regulator-compatible = "ldo5"; 171 reg = <8>; 172 regulator-min-microvolt = <1000000>; 173 regulator-max-microvolt = <3300000>; 174 ti,regulator-ext-sleep-control = <0>; 175 }; 176 ldo6_reg: regulator@9 { 177 regulator-compatible = "ldo6"; 178 reg = <9>; 179 regulator-min-microvolt = <1200000>; 180 regulator-max-microvolt = <1200000>; 181 ti,regulator-ext-sleep-control = <0>; 182 }; 183 ldo7_reg: regulator@10 { 184 regulator-compatible = "ldo7"; 185 reg = <10>; 186 regulator-min-microvolt = <1200000>; 187 regulator-max-microvolt = <1200000>; 188 regulator-always-on; 189 regulator-boot-on; 190 ti,regulator-ext-sleep-control = <1>; 191 }; 192 ldo8_reg: regulator@11 { 193 regulator-compatible = "ldo8"; 194 reg = <11>; 195 regulator-min-microvolt = <1000000>; 196 regulator-max-microvolt = <3300000>; 197 regulator-always-on; 198 ti,regulator-ext-sleep-control = <1>; 199 }; 200 }; 201 }; 202
