+Device-Tree bindings for charger of Active-semi ACT8945A Multi-Function Device
+
+Required properties:
+ - compatible: "active-semi,act8945a", please refer to ../mfd/act8945a.txt.
+ - active-semi,chglev-gpios: charge current level phandle with args
+ as described in ../gpio/gpio.txt.
+
+Optional properties:
+ - active-semi,check-battery-temperature: boolean to check the battery
+ temperature or not.
+ - 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>;
+ status = "okay";
+
+ pinctrl-names = "default";
+ pinctrl-0 = <&pinctrl_charger_chglev>;
+ active-semi,chglev-gpios = <&pioA 12 GPIO_ACTIVE_HIGH>;
+ active-semi,input-voltage-threshold-microvolt = <6600>;
+ active-semi,precondition-timeout = <40>;
+ active-semi,total-timeout = <3>;
+ };
