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 GPIO_ACTIVE_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>;
};
};
