-Device-Tree bindings for charger of Active-semi ACT8945A Multi-Function Device
-
-Required properties:
- - compatible: "active-semi,act8945a-charger".
- - active-semi,chglev-gpios: charge current level phandle with args
- as described in ../gpio/gpio.txt.
- - active-semi,lbo-gpios: specify the low battery voltage detect phandle
- with args as as described in ../gpio/gpio.txt.
- - interrupts: <a b> where a is the interrupt number and b is a
- field that represents an encoding of the sense and level
- information for the interrupt.
-
-Optional properties:
- - active-semi,input-voltage-threshold-microvolt: unit: mV;
- Specifies the charger's input over-voltage threshold value;
- The value can be: 6600, 7000, 7500, 8000; default: 6600
- - active-semi,precondition-timeout: unit: minutes;
- Specifies the charger's PRECONDITION safety timer setting value;
- The value can be: 40, 60, 80, 0; If 0, it means to disable this timer;
- default: 40.
- - active-semi,total-timeout: unit: hours;
- Specifies the charger's total safety timer setting value;
- The value can be: 3, 4, 5, 0; If 0, it means to disable this timer;
- default: 3.
-
-Example:
- pmic@5b {
- compatible = "active-semi,act8945a";
- reg = <0x5b>;
-
- charger {
- compatible = "active-semi,act8945a-charger";
- pinctrl-names = "default";
- pinctrl-0 = <&pinctrl_charger_chglev &pinctrl_charger_lbo &pinctrl_charger_irq>;
- interrupt-parent = <&pioA>;
- interrupts = <45 IRQ_TYPE_LEVEL_LOW>;
-
- active-semi,chglev-gpios = <&pioA 12 GPIO_ACTIVE_HIGH>;
- active-semi,lbo-gpios = <&pioA 72 GPIO_ACTIVE_LOW>;
- active-semi,input-voltage-threshold-microvolt = <6600>;
- active-semi,precondition-timeout = <40>;
- active-semi,total-timeout = <3>;
- };
