* 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>;
};
