| * 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>; | |
| }; |
