1*c66ec88fSEmmanuel Vadot* NXP LPC32xx SoC USB Device Controller (UDC)
2*c66ec88fSEmmanuel Vadot
3*c66ec88fSEmmanuel VadotRequired properties:
4*c66ec88fSEmmanuel Vadot- compatible: Must be "nxp,lpc3220-udc"
5*c66ec88fSEmmanuel Vadot- reg: Physical base address of the controller and length of memory mapped
6*c66ec88fSEmmanuel Vadot  region.
7*c66ec88fSEmmanuel Vadot- interrupts: The USB interrupts:
8*c66ec88fSEmmanuel Vadot              * USB Device Low Priority Interrupt
9*c66ec88fSEmmanuel Vadot              * USB Device High Priority Interrupt
10*c66ec88fSEmmanuel Vadot              * USB Device DMA Interrupt
11*c66ec88fSEmmanuel Vadot              * External USB Transceiver Interrupt (OTG ATX)
12*c66ec88fSEmmanuel Vadot- transceiver: phandle of the associated ISP1301 device - this is necessary for
13*c66ec88fSEmmanuel Vadot               the UDC controller for connecting to the USB physical layer
