   5
   6 Required properties :
   7  - compatible: should be one or more of:
   8    - "marvell,armada3700-xhci", "generic-xhci" for Armada 37xx SoCs
   9    - "marvell,armada-8k-xhci", "generic-xhci" for Armada A8K SoCs
  10  - reg: should contain address and length of the standard XHCI
  11    register set for the device.
  12  - interrupts: one XHCI interrupt should be described here.
  13
  14 Optional properties:
  15  - clocks: phandle to system controller clock driving this unit

  19 Example:
  20         cpm_usb3_0: usb3@500000 {
  21                 compatible = "marvell,armada-8k-xhci",
  22                              "generic-xhci";
  23                 reg = <0x500000 0x4000>;
  24                 interrupts = <GIC_SPI 62 IRQ_TYPE_LEVEL_HIGH>;
  25                 clocks = <&cpm_syscon0 1 22>;
  26                 vbus-supply = <&reg_usb3h0_vbus>;
  27                 status = "disabled";
  28         };
