dt-bindings: power: supply: act8945a: Convert to DT schema format

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>;

		};
