+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
+    - "brcm,bcm7445-xhci" for Broadcom STB SoCs with XHCI
+    - "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 the clocks
+  - clock-names: mandatory if there is a second clock, in this case
+    the name must be "core" for the first clock and "reg" for the
+    second one
+  - usb2-lpm-disable: indicate if we don't want to enable USB2 HW LPM
+  - usb3-lpm-capable: determines if platform is USB3 LPM capable
+  - quirk-broken-port-ped: set if the controller has broken port disable mechanism
+  - imod-interval-ns: default interrupt moderation interval is 5000ns
+  - phys : see usb-hcd.yaml in the current directory
+
+additionally the properties from usb-hcd.yaml (in the current directory) are
+supported.
+
+
+Example:
+	usb@f0931000 {
+		compatible = "generic-xhci";
+		reg = <0xf0931000 0x8c8>;
+		interrupts = <0x0 0x4e 0x0>;
+	};
