  1. Marvell SOC USB controllers
  2. This controller is integrated in Armada 3700/8K.
  3. It uses the same properties as a generic XHCI host controller
  4. Required properties :
  5. - compatible: should be one or more of:
  6. - "marvell,armada3700-xhci", "generic-xhci" for Armada 37xx SoCs
  7. - "marvell,armada-8k-xhci", "generic-xhci" for Armada A8K SoCs
  8. - reg: should contain address and length of the standard XHCI
  9. register set for the device.
  10. - interrupts: one XHCI interrupt should be described here.
  11. Optional properties:
  12. - clocks: phandle to system controller clock driving this unit
  13. - vbus-supply : If present, specifies the fixed regulator to be turned on
  14. for providing power to the USB VBUS rail.
  15. Example:
  16. cpm_usb3_0: usb3@500000 {
  17. compatible = "marvell,armada-8k-xhci",
  18. "generic-xhci";
  19. reg = <0x500000 0x4000>;
  20. interrupts = <GIC_SPI 62 IRQ_TYPE_LEVEL_HIGH>;
  21. clocks = <&cpm_syscon0 1 22>;
  22. vbus-supply = <&reg_usb3h0_vbus>;
  23. status = "disabled";
  24. };
