    q) USB EHCI controllers



    Required properties:

      - compatible : should be "usb-ehci".

      - reg : should contain at least address and length of the standard EHCI

        register set for the device. Optional platform-dependent registers

        (debug-port or other) can be also specified here, but only after

        definition of standard EHCI registers.

      - interrupts : one EHCI interrupt should be described here.

    If device registers are implemented in big endian mode, the device

    node should have "big-endian-regs" property.

    If controller implementation operates with big endian descriptors,

    "big-endian-desc" property should be specified.

    If both big endian registers and descriptors are used by the controller

    implementation, "big-endian" property can be specified instead of having

    both "big-endian-regs" and "big-endian-desc".



     Example (Sequoia 440EPx):

	    ehci@e0000300 {

		   compatible = "ibm,usb-ehci-440epx", "usb-ehci";

		   interrupt-parent = <&UIC0>;

		   interrupts = <1a 4>;

		   reg = <0 e0000300 90 0 e0000390 70>;

		   big-endian;

	   };





   More devices will be defined as this spec matures.
