| * 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>; |
| }; |
