| Roland Stigge | 24a28e4 | 2012-04-29 16:47:05 +0200 | [diff] [blame] | 1 | * NXP LPC32xx SoC USB Device Controller (UDC) |
| 2 | |
| 3 | Required properties: |
| 4 | - compatible: Must be "nxp,lpc3220-udc" |
| 5 | - reg: Physical base address of the controller and length of memory mapped |
| 6 | region. |
| 7 | - interrupts: The USB interrupts: |
| 8 | * USB Device Low Priority Interrupt |
| 9 | * USB Device High Priority Interrupt |
| 10 | * USB Device DMA Interrupt |
| 11 | * External USB Transceiver Interrupt (OTG ATX) |
| 12 | - transceiver: phandle of the associated ISP1301 device - this is necessary for |
| 13 | the UDC controller for connecting to the USB physical layer |
| 14 | |
| 15 | Example: |
| 16 | |
| 17 | isp1301: usb-transceiver@2c { |
| 18 | compatible = "nxp,isp1301"; |
| 19 | reg = <0x2c>; |
| 20 | }; |
| 21 | |
| 22 | usbd@31020000 { |
| 23 | compatible = "nxp,lpc3220-udc"; |
| 24 | reg = <0x31020000 0x300>; |
| 25 | interrupt-parent = <&mic>; |
| 26 | interrupts = <0x3d 0>, <0x3e 0>, <0x3c 0>, <0x3a 0>; |
| 27 | transceiver = <&isp1301>; |
| 28 | }; |
