   2
   3 Required properties:
   4   - compatible: should be one or more of
   5
   6     - "generic-xhci" for generic XHCI device
   7     - "marvell,armada3700-xhci" for Armada 37xx SoCs
   8     - "marvell,armada-375-xhci" for Armada 375 SoCs
   9     - "marvell,armada-380-xhci" for Armada 38x SoCs
  10     - "renesas,xhci-r8a7790" for r8a7790 SoC
  11     - "renesas,xhci-r8a7791" for r8a7791 SoC
  12     - "renesas,xhci-r8a7793" for r8a7793 SoC
  13     - "renesas,xhci-r8a7795" for r8a7795 SoC
  14     - "renesas,xhci-r8a7796" for r8a7796 SoC
  15     - "renesas,xhci-r8a77965" for r8a77965 SoC
  16     - "renesas,rcar-gen2-xhci" for a generic R-Car Gen2 compatible device
  17     - "renesas,rcar-gen3-xhci" for a generic R-Car Gen3 compatible device
  18     - "xhci-platform" (deprecated)
  19
  20     When compatible with the generic version, nodes must list the
  21     SoC-specific version corresponding to the platform first
  22     followed by the generic version.
  23
  24   - reg: should contain address and length of the standard XHCI
  25     register set for the device.
  26   - interrupts: one XHCI interrupt should be described here.
  27
  28 Optional properties:
  29   - clocks: reference to a clock
  30   - usb3-lpm-capable: determines if platform is USB3 LPM capable
  31   - quirk-broken-port-ped: set if the controller has broken port disable mechanism
  32
  33 Example:
  34         usb@f0931000 {
  35                 compatible = "generic-xhci";
  36                 reg = <0xf0931000 0x8c8>;
  37                 interrupts = <0x0 0x4e 0x0>;
  38         };
