+* 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>;

+                reg = <0x31020000 0x300>;
+                interrupt-parent = <&mic>;
+                interrupts = <0x3d 0>, <0x3e 0>, <0x3c 0>, <0x3a 0>;
+                transceiver = <&isp1301>;
+                status = "okay";
+        };

+* NXP LPC32xx SoC USB Device Controller (UDC)
+
+Required properties:
+- compatible: Must be "nxp,lpc3220-udc"
+- reg: Physical base address of the controller and length of memory mapped
+  region.
+- interrupts: The USB interrupts:
+              * USB Device Low Priority Interrupt
+              * USB Device High Priority Interrupt
+              * USB Device DMA Interrupt

+- transceiver: phandle of the associated ISP1301 device - this is necessary for
+               the UDC controller for connecting to the USB physical layer
+
+Example:
+
+        isp1301: usb-transceiver@2c {
