+* Freescale QorIQ SoC USB 2.0 Controllers
+
+Required properties:
+- compatible: Should be "fsl,ci-qoriq-usb2"
+  Wherever applicable, the IP version of the USB controller should
+  also be mentioned (for eg. fsl,ci-qoriq-usb2-vX.Y).
+  where, X.Y is IP version of USB controller.
+- reg: Should contain registers location and length
+- interrupts: Should contain controller interrupt
+- phy-names: from the *Generic PHY* bindings
+- phys: from the *Generic PHY* bindings
+- clocks: clock provider specifier
+- clock-names: shall be "usb2-clock"
+Refer to clk/clock-bindings.txt for generic clock consumer properties
+
+Recommended properties:
+- dr_mode: One of "host" or "peripheral".
+- phy_type: the type of the phy connected to the core. Should be one
+  of "utmi", "utmi_wide", "ulpi", "serial" or "hsic". Without this
+  property the PORTSC register won't be touched
+
+Examples:
+usb@8600000 {
+       compatible =  "fsl,ci-qoriq-usb2",
+                     "fsl,ci-qoriq-usb2-v2.5";
+       reg = <0x0 0x8600000 0x0 0x1000>;
+       interrupts = <0 139 0x4>;
+       phy-names = "usb2-phy";
+       phys = <&usbphy0>;
+       clock-names = "usb2-clock";
+       clocks = <&clockgen 4 3>;
+       dr_mode = "host";
+       phy_type = "ulpi";
+};
