* 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 >;
|
|
};
