Kernel-4.18.0-80.el8_usb-xhci

USB xHCI controllers

Required properties:

• compatible: should be one or more of

  • “generic-xhci” for generic XHCI device
  • “marvell,armada3700-xhci” for Armada 37xx SoCs
  • “marvell,armada-375-xhci” for Armada 375 SoCs
  • “marvell,armada-380-xhci” for Armada 38x SoCs
  • “renesas,xhci-r8a7743” for r8a7743 SoC
  • “renesas,xhci-r8a7790” for r8a7790 SoC
  • “renesas,xhci-r8a7791” for r8a7791 SoC
  • “renesas,xhci-r8a7793” for r8a7793 SoC
  • “renesas,xhci-r8a7795” for r8a7795 SoC
  • “renesas,xhci-r8a7796” for r8a7796 SoC
  • “renesas,xhci-r8a77965” for r8a77965 SoC
  • “renesas,rcar-gen2-xhci” for a generic R-Car Gen2 or RZ/G1 compatible
    device
  • “renesas,rcar-gen3-xhci” for a generic R-Car Gen3 compatible device
  • “xhci-platform” (deprecated)

  When compatible with the generic version, nodes must list the
  SoC-specific version corresponding to the platform first
  followed by the generic version.

• reg: should contain address and length of the standard XHCI
  register set for the device.

• interrupts: one XHCI interrupt should be described here.

Optional properties:

• clocks: reference to the clocks
• clock-names: mandatory if there is a second clock, in this case
  the name must be “core” for the first clock and “reg” for the
  second one
• usb2-lpm-disable: indicate if we don’t want to enable USB2 HW LPM
• usb3-lpm-capable: determines if platform is USB3 LPM capable
• quirk-broken-port-ped: set if the controller has broken port disable mechanism
• imod-interval-ns: default interrupt moderation interval is 5000ns
• phys : see usb-hcd.txt in the current directory

additionally the properties from usb-hcd.txt (in the current directory) are
supported.

Example:
usb@f0931000 {
compatible = “generic-xhci”;
reg = <0xf0931000 0x8c8>;
interrupts = <0x0 0x4e 0x0>;
};
