+  Required properties:
+  - device_type : should be "usb".
+  - compatible : should be "ehci".
+  - reg : Offset and length of the register set for the device
+  - interrupts : <a b> where a is the interrupt number and b is a
+    field that represents an encoding of the sense and level
+    information for the interrupt.  This should be encoded based on
+    the information in section 2) depending on the type of interrupt
+    controller you have.
+  - interrupt-parent : the phandle for the interrupt controller that
+    services interrupts for this device.
+  If device registers are implemented in big endian mode, the device
+  node should have "big-endian" property.
+  If controller implementation operates with big endian descriptors,
+  compatible should also have "ehci-be-desc"
+
+   Example (Sequoia 440EPx):
+	ehci at e0000300 {
+		device_type = "usb";
+		compatible = "ibm,ehci-440epx", "ehci-be-desc", "ehci";
+		interrupts = <1a 4>;
+		interrupt-parent = <&UIC0>;
+		reg = <0 e0000300 ff>;
+		big-endian;
+	};

    More devices will be defined as this spec matures.
