+* 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";
+       };
