* AHCI SATA Controller
|
|
|
|
SATA nodes are defined to describe on-chip Serial ATA controllers.
|
|
Each SATA controller should have its own node.
|
|
|
|
Required properties:
|
|
- compatible : compatible list, contains "calxeda,hb-ahci" or "snps,spear-ahci"
|
|
- interrupts : <interrupt mapping for SATA IRQ>
|
|
- reg : <registers mapping>
|
|
|
|
Optional properties:
|
|
- dma-coherent : Present if dma operations are coherent
|
|
|
|
Example:
|
|
sata@ffe08000 {
|
|
compatible = "calxeda,hb-ahci";
|
|
reg = <0xffe08000 0x1000>;
|
|
interrupts = <115>;
|
|
};
