1* Marvell 88PM860x Power Management IC 2 3Required parent device properties: 4- compatible : "marvell,88pm860x" 5- reg : the I2C slave address for the 88pm860x chip 6- interrupts : IRQ line for the 88pm860x chip 7- interrupt-controller: describes the 88pm860x as an interrupt controller (has its own domain) 8- #interrupt-cells : should be 1. 9 - The cell is the 88pm860x local IRQ number 10 11Optional parent device properties: 12- marvell,88pm860x-irq-read-clr: inicates whether interrupt status is cleared by read 13- marvell,88pm860x-slave-addr: 88pm860x are two chips solution. <reg> stores the I2C address 14 of one chip, and this property stores the I2C address of 15 another chip. 16 1788pm860x consists of a large and varied group of sub-devices: 18 19Device Supply Names Description 20------ ------------ ----------- 2188pm860x-onkey : : On key 2288pm860x-rtc : : RTC 2388pm8607 : : Regulators 2488pm860x-backlight : : Backlight 2588pm860x-led : : Led 2688pm860x-touch : : Touchscreen 27 28Example: 29 30 pmic: 88pm860x@34 { 31 compatible = "marvell,88pm860x"; 32 reg = <0x34>; 33 interrupts = <4>; 34 interrupt-parent = <&intc>; 35 interrupt-controller; 36 #interrupt-cells = <1>; 37 38 marvell,88pm860x-irq-read-clr; 39 marvell,88pm860x-slave-addr = <0x11>; 40 41 regulators { 42 BUCK1 { 43 regulator-min-microvolt = <1000000>; 44 regulator-max-microvolt = <1500000>; 45 regulator-boot-on; 46 regulator-always-on; 47 }; 48 LDO1 { 49 regulator-min-microvolt = <1200000>; 50 regulator-max-microvolt = <2800000>; 51 regulator-boot-on; 52 regulator-always-on; 53 }; 54 }; 55 rtc { 56 marvell,88pm860x-vrtc = <1>; 57 }; 58 touch { 59 marvell,88pm860x-gpadc-prebias = <1>; 60 marvell,88pm860x-gpadc-slot-cycle = <1>; 61 marvell,88pm860x-tsi-prebias = <6>; 62 marvell,88pm860x-pen-prebias = <16>; 63 marvell,88pm860x-pen-prechg = <2>; 64 marvell,88pm860x-resistor-X = <300>; 65 }; 66 backlights { 67 backlight-0 { 68 marvell,88pm860x-iset = <4>; 69 marvell,88pm860x-pwm = <3>; 70 }; 71 backlight-2 { 72 }; 73 }; 74 leds { 75 led0-red { 76 marvell,88pm860x-iset = <12>; 77 }; 78 led0-green { 79 marvell,88pm860x-iset = <12>; 80 }; 81 led0-blue { 82 marvell,88pm860x-iset = <12>; 83 }; 84 }; 85 }; 86
