+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>;
+ };
