+ 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@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.
