  1. Maxim Integrated SPI-based USB 2.0 host controller MAX3421E
  2. Required properties:
  3. - compatible: Should be "maxim,max3421"
  4. - spi-max-frequency: maximum frequency for this device must not exceed 26 MHz.
  5. - reg: chip select number to which this device is connected.
  6. - maxim,vbus-en-pin: <GPOUTx ACTIVE_LEVEL>
  7. GPOUTx is the number (1-8) of the GPOUT pin of MAX3421E to drive Vbus.
  8. ACTIVE_LEVEL is 0 or 1.
  9. - interrupts: the interrupt line description for the interrupt controller.
  10. The driver configures MAX3421E for active low level triggered interrupts,
  11. configure your interrupt line accordingly.
  12. Example:
  13. usb@0 {
  14. compatible = "maxim,max3421";
  15. reg = <0>;
  16. maxim,vbus-en-pin = <3 1>;
  17. spi-max-frequency = <26000000>;
  18. interrupt-parent = <&PIC>;
  19. interrupts = <42>;
  20. };
