* 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.
