-Binding for NXP ISP1704 USB Charger Detection
-
-Required properties:
-- compatible: Should contain one of the following:
- * "nxp,isp1704"
-- nxp,enable-gpio: Should contain a phandle + gpio-specifier
-  to the GPIO pin connected to the chip's enable pin.
-- usb-phy: Should contain a phandle to the USB PHY
-  the ISP1704 is connected to.
-
-Example:
-
-isp1704 {
-	compatible = "nxp,isp1704";
-	nxp,enable-gpio = <&gpio3 3 GPIO_ACTIVE_LOW>;
-	usb-phy = <&usb2_phy>;
-};
