   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

  19     - "renesas,xhci-r8a7796" for r8a7796 SoC
  20     - "renesas,xhci-r8a77965" for r8a77965 SoC
  21     - "renesas,xhci-r8a77990" for r8a77990 SoC
  22     - "renesas,rcar-gen2-xhci" for a generic R-Car Gen2 or RZ/G1 compatible
  23       device
  24     - "renesas,rcar-gen3-xhci" for a generic R-Car Gen3 or RZ/G2 compatible
  25       device
  26     - "xhci-platform" (deprecated)
  27
  28     When compatible with the generic version, nodes must list the
  29     SoC-specific version corresponding to the platform first
  30     followed by the generic version.
  31
  32   - reg: should contain address and length of the standard XHCI
  33     register set for the device.
  34   - interrupts: one XHCI interrupt should be described here.
  35
  36 Optional properties:
  37   - clocks: reference to the clocks
  38   - clock-names: mandatory if there is a second clock, in this case
  39     the name must be "core" for the first clock and "reg" for the
  40     second one
  41   - usb2-lpm-disable: indicate if we don't want to enable USB2 HW LPM
  42   - usb3-lpm-capable: determines if platform is USB3 LPM capable
  43   - quirk-broken-port-ped: set if the controller has broken port disable mechanism
  44   - imod-interval-ns: default interrupt moderation interval is 5000ns
  45   - phys : see usb-hcd.yaml in the current directory
  46
  47 additionally the properties from usb-hcd.yaml (in the current directory) are
  48 supported.

  51 Example:
  52         usb@f0931000 {
  53                 compatible = "generic-xhci";
  54                 reg = <0xf0931000 0x8c8>;
  55                 interrupts = <0x0 0x4e 0x0>;
  56         };
