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    - "brcm,bcm7445-xhci" for Broadcom STB SoCs with XHCI
11    - "xhci-platform" (deprecated)
12
13    When compatible with the generic version, nodes must list the
14    SoC-specific version corresponding to the platform first
15    followed by the generic version.
16
17  - reg: should contain address and length of the standard XHCI
18    register set for the device.
19  - interrupts: one XHCI interrupt should be described here.
20
21Optional properties:
22  - clocks: reference to the clocks
23  - clock-names: mandatory if there is a second clock, in this case
24    the name must be "core" for the first clock and "reg" for the
25    second one
26  - usb2-lpm-disable: indicate if we don't want to enable USB2 HW LPM
27  - usb3-lpm-capable: determines if platform is USB3 LPM capable
28  - quirk-broken-port-ped: set if the controller has broken port disable mechanism
29  - imod-interval-ns: default interrupt moderation interval is 5000ns
30  - phys : see usb-hcd.yaml in the current directory
31
32additionally the properties from usb-hcd.yaml (in the current directory) are
33supported.

36Example:
37	usb@f0931000 {
38		compatible = "generic-xhci";
39		reg = <0xf0931000 0x8c8>;
40		interrupts = <0x0 0x4e 0x0>;
41	};
