1*4882a593Smuzhiyun* NXP LPC32xx SoC USB Device Controller (UDC)
2*4882a593Smuzhiyun
3*4882a593SmuzhiyunRequired properties:
4*4882a593Smuzhiyun- compatible: Must be "nxp,lpc3220-udc"
5*4882a593Smuzhiyun- reg: Physical base address of the controller and length of memory mapped
6*4882a593Smuzhiyun  region.
7*4882a593Smuzhiyun- interrupts: The USB interrupts:
8*4882a593Smuzhiyun              * USB Device Low Priority Interrupt
9*4882a593Smuzhiyun              * USB Device High Priority Interrupt
10*4882a593Smuzhiyun              * USB Device DMA Interrupt
11*4882a593Smuzhiyun              * External USB Transceiver Interrupt (OTG ATX)
12*4882a593Smuzhiyun- transceiver: phandle of the associated ISP1301 device - this is necessary for
13*4882a593Smuzhiyun               the UDC controller for connecting to the USB physical layer
