gpio-charger



Required properties :

 - compatible : "gpio-charger"

 - gpios : GPIO indicating the charger presence.

   See GPIO binding in bindings/gpio/gpio.txt .

 - charger-type : power supply type, one of

     unknown

     battery

     ups

     mains

     usb-sdp (USB standard downstream port)

     usb-dcp (USB dedicated charging port)

     usb-cdp (USB charging downstream port)

     usb-aca (USB accessory charger adapter)



Optional properties:

 - charge-status-gpios: GPIO indicating whether a battery is charging.



Example:



	usb_charger: charger {

		compatible = "gpio-charger";

		charger-type = "usb-sdp";

		gpios = <&gpd 28 GPIO_ACTIVE_LOW>;

		charge-status-gpios = <&gpc 27 GPIO_ACTIVE_LOW>;

	};



	battery {

		power-supplies = <&usb_charger>;

	};

description:

  This binding is for all chargers, which are working more or less

  autonomously, only providing some status GPIOs and possibly some

  GPIOs for limited control over the charging process.
