1TI LP873X PMIC MFD driver 2 3Required properties: 4 - compatible: "ti,lp8732", "ti,lp8733" 5 - reg: I2C slave address. 6 - gpio-controller: Marks the device node as a GPIO Controller. 7 - #gpio-cells: Should be two. The first cell is the pin number and 8 the second cell is used to specify flags. 9 See ../gpio/gpio.txt for more information. 10 - xxx-in-supply: Phandle to parent supply node of each regulator 11 populated under regulators node. xxx can be 12 buck0, buck1, ldo0 or ldo1. 13 - regulators: List of child nodes that specify the regulator 14 initialization data. 15Example: 16 17pmic: lp8733@60 { 18 compatible = "ti,lp8733"; 19 reg = <0x60>; 20 gpio-controller; 21 #gpio-cells = <2>; 22 23 buck0-in-supply = <&vsys_3v3>; 24 buck1-in-supply = <&vsys_3v3>; 25 ldo0-in-supply = <&vsys_3v3>; 26 ldo1-in-supply = <&vsys_3v3>; 27 28 regulators { 29 lp8733_buck0: buck0 { 30 regulator-name = "lp8733-buck0"; 31 regulator-min-microvolt = <800000>; 32 regulator-max-microvolt = <1400000>; 33 regulator-min-microamp = <1500000>; 34 regulator-max-microamp = <4000000>; 35 regulator-ramp-delay = <10000>; 36 regulator-always-on; 37 regulator-boot-on; 38 }; 39 40 lp8733_buck1: buck1 { 41 regulator-name = "lp8733-buck1"; 42 regulator-min-microvolt = <800000>; 43 regulator-max-microvolt = <1400000>; 44 regulator-min-microamp = <1500000>; 45 regulator-max-microamp = <4000000>; 46 regulator-ramp-delay = <10000>; 47 regulator-boot-on; 48 regulator-always-on; 49 }; 50 51 lp8733_ldo0: ldo0 { 52 regulator-name = "lp8733-ldo0"; 53 regulator-min-microvolt = <800000>; 54 regulator-max-microvolt = <3000000>; 55 regulator-boot-on; 56 regulator-always-on; 57 }; 58 59 lp8733_ldo1: ldo1 { 60 regulator-name = "lp8733-ldo1"; 61 regulator-min-microvolt = <800000>; 62 regulator-max-microvolt = <3000000>; 63 regulator-always-on; 64 regulator-boot-on; 65 }; 66 }; 67}; 68
