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-r8a7744" for r8a7744 SoC - "renesas,xhci-r8a774a1" for r8a774a1 SoC - "renesas,xhci-r8a774c0" for r8a774c0 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,xhci-r8a77990" for r8a77990 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 or RZ/G2 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>; };
