+* 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
+ * External USB Transceiver Interrupt (OTG ATX)
+- 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 {
+ 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>;
+ };
