USB xHCI controllers
Required properties:
- - compatible: should be one of "generic-xhci",
- "marvell,armada-375-xhci", "marvell,armada-380-xhci",
- "renesas,xhci-r8a7790", "renesas,xhci-r8a7791", "renesas,xhci-r8a7793",
- "renesas,xhci-r8a7795" (deprecated: "xhci-platform").
+ - compatible: should be one or more of
+
+ - "generic-xhci" for generic XHCI device
+ - "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.
