1USB xHCI controllers
2
3Required properties:
4  - compatible: should be one or more of
5
6    - "generic-xhci" for generic XHCI device
7    - "marvell,armada3700-xhci" for Armada 37xx SoCs
8    - "marvell,armada-375-xhci" for Armada 375 SoCs
9    - "marvell,armada-380-xhci" for Armada 38x SoCs
10    - "renesas,xhci-r8a7790" for r8a7790 SoC
11    - "renesas,xhci-r8a7791" for r8a7791 SoC
12    - "renesas,xhci-r8a7793" for r8a7793 SoC
13    - "renesas,xhci-r8a7795" for r8a7795 SoC
14    - "renesas,rcar-gen2-xhci" for a generic R-Car Gen2 compatible device
15    - "renesas,rcar-gen3-xhci" for a generic R-Car Gen3 compatible device
16    - "xhci-platform" (deprecated)
17
18    When compatible with the generic version, nodes must list the
19    SoC-specific version corresponding to the platform first
20    followed by the generic version.
21
22  - reg: should contain address and length of the standard XHCI
23    register set for the device.
24  - interrupts: one XHCI interrupt should be described here.
25
26Optional properties:
27  - clocks: reference to a clock
28  - usb3-lpm-capable: determines if platform is USB3 LPM capable
29  - quirk-broken-port-ped: set if the controller has broken port disable mechanism
30
31Example:
32        usb@f0931000 {
33                compatible = "generic-xhci";
34                reg = <0xf0931000 0x8c8>;
35                interrupts = <0x0 0x4e 0x0>;
36        };
