-Required properties :
- - compatible : "gpio-charger"
- - 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:
- - gpios : GPIO indicating the charger presence.
- See GPIO binding in bindings/gpio/gpio.txt .
- - charge-status-gpios: GPIO indicating whether a battery is charging.
- - charge-current-limit-gpios: Output GPIOs specifiers for limiting the charge current
- - charge-current-limit-mapping: List of touples with current in uA and a GPIO bitmap (in this order).
- The GPIOs are encoded in the same order as specified in charge-current-limit-gpios.
- The touples must be provided in descending order of the current limit.
-
-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>;
-
- charge-current-limit-gpios = <&gpioA 11 GPIO_ACTIVE_HIGH>, <&gpioA 12 GPIO_ACTIVE_HIGH>;
- charge-current-limit-mapping = <2500000 0x00>, <700000 0x01>, <0 0x02>;
- };
-
- 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
