Android Goldfish Battery



Android goldfish battery device generated by android emulator.



Required properties:



- compatible : should contain "google,goldfish-battery" to match emulator

- reg        : <registers mapping>

- interrupts : <interrupt mapping>



Example:



	goldfish_battery@9020000 {

		compatible = "google,goldfish-battery";

		reg = <0x9020000 0x1000>;

		interrupts = <0x3>;

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>;

	};
