+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>;
+		};
+	};
