- 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-r8a7790" for r8a7790 SoC
- - "renesas,xhci-r8a7791" for r8a7791 SoC
- - "renesas,xhci-r8a7793" for r8a7793 SoC
- - "renesas,xhci-r8a7795" for r8a7795 SoC
- - "renesas,rcar-gen2-xhci" for a generic R-Car Gen2 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 a clock
- - usb3-lpm-capable: determines if platform is USB3 LPM capable
- - quirk-broken-port-ped: set if the controller has broken port disable mechanism
- Example:
- usb@f0931000 {
- compatible = "generic-xhci";
- reg = <0xf0931000 0x8c8>;
- interrupts = <0x0 0x4e 0x0>;
- };
