* NXP ISP1301 USB transceiver

Required properties:
- compatible: must be "nxp,isp1301"
- reg: I2C address of the ISP1301 device

Optional properties of devices using ISP1301:
- transceiver: phandle of isp1301 - this helps the ISP1301 driver to find the
               ISP1301 instance associated with the respective USB driver

Example:

	isp1301: usb-transceiver@2c {
		compatible = "nxp,isp1301";
		reg = <0x2c>;
	};

	usbd@31020000 {
		compatible = "nxp,lpc3220-udc";
		reg = <0x31020000 0x300>;
		interrupt-parent = <&mic>;
		interrupts = <0x3d 0>, <0x3e 0>, <0x3c 0>, <0x3a 0>;
		transceiver = <&isp1301>;
		status = "okay";
	};
