+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

+     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)

+Example:
