| * 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 "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 = "snps,spear-ahci"; | |
| reg = <0xffe08000 0x1000>; | |
| interrupts = <115>; | |
| }; |
