2746 * Freescale 8xxx/3.0 Gb/s SATA nodes
2747
2748 SATA nodes are defined to describe on-chip Serial ATA controllers.
2749 Each SATA port should have its own node.
2750
2751 Required properties:
2752 - compatible : compatible list, contains 2 entries, first is
2753 "fsl,CHIP-sata", where CHIP is the processor
2754 (mpc8315, mpc8379, etc.) and the second is
2755 "fsl,pq-sata"
2756 - interrupts : <interrupt mapping for SATA IRQ>
2757 - cell-index : controller index.
2758 1 for controller @ 0x18000
2759 2 for controller @ 0x19000
2760 3 for controller @ 0x1a000
2761 4 for controller @ 0x1b000
2762
2763 Optional properties:
2764 - interrupt-parent : optional, if needed for interrupt mapping
2765 - reg : <registers mapping>
2766
2767 Example:
2768
2769 sata@18000 {
2770 compatible = "fsl,mpc8379-sata", "fsl,pq-sata";
2771 reg = <0x18000 0x1000>;
2772 cell-index = <1>;
2773 interrupts = <2c 8>;
2774 interrupt-parent = < &ipic >;
2775 };
