1* NXP LPC32xx SoC USB Device Controller (UDC)
2
3Required properties:
4- compatible: Must be "nxp,lpc3220-udc"
5- reg: Physical base address of the controller and length of memory mapped
6  region.
7- interrupts: The USB interrupts:
8              * USB Device Low Priority Interrupt
9              * USB Device High Priority Interrupt
10              * USB Device DMA Interrupt
11              * External USB Transceiver Interrupt (OTG ATX)
12- transceiver: phandle of the associated ISP1301 device - this is necessary for
13               the UDC controller for connecting to the USB physical layer
14
15Example:
16
17	isp1301: usb-transceiver@2c {
18		compatible = "nxp,isp1301";
19		reg = <0x2c>;
20	};
21
22	usbd@31020000 {
23		compatible = "nxp,lpc3220-udc";
24		reg = <0x31020000 0x300>;
25		interrupt-parent = <&mic>;
26		interrupts = <0x3d 0>, <0x3e 0>, <0x3c 0>, <0x3a 0>;
27		transceiver = <&isp1301>;
28	};
