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>;
};

title: simple battery chargers only communicating through GPIOs
maintainers:

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.
