USB xHCI controllers
|
|
|
|
Required properties:
|
|
- 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.
|
|
|
|
Optional properties:
|
|
- clocks: reference to a clock
|
|
- usb3-lpm-capable: determines if platform is USB3 LPM capable
|
|
|
|
Example:
|
|
usb@f0931000 {
|
|
compatible = "generic-xhci";
|
|
reg = <0xf0931000 0x8c8>;
|
|
interrupts = <0x0 0x4e 0x0>;
|
|
};
