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>; | ||
