    * Freescale 8xxx/3.0 Gb/s SATA nodes



    SATA nodes are defined to describe on-chip Serial ATA controllers.

    Each SATA port should have its own node.



    Required properties:

    - compatible        : compatible list, contains 2 entries, first is

			 "fsl,CHIP-sata", where CHIP is the processor

			 (mpc8315, mpc8379, etc.) and the second is

			 "fsl,pq-sata"

    - interrupts        : <interrupt mapping for SATA IRQ>

    - cell-index        : controller index.

                              1 for controller @ 0x18000

                              2 for controller @ 0x19000

                              3 for controller @ 0x1a000

                              4 for controller @ 0x1b000



    Optional properties:

    - interrupt-parent  : optional, if needed for interrupt mapping

    - reg               : <registers mapping>



   Example:



	sata@18000 {

		compatible = "fsl,mpc8379-sata", "fsl,pq-sata";

		reg = <0x18000 0x1000>;

		cell-index = <1>;

		interrupts = <2c 8>;

		interrupt-parent = < &ipic >;

        };





   More devices will be defined as this spec matures.
