| * 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: |
| - calxeda,port-phys: phandle-combophy and lane assignment, which maps each |
| SATA port to a combophy and a lane within that |
| combophy |
| - dma-coherent : Present if dma operations are coherent |
| |
| Example: |
| sata@ffe08000 { |
| compatible = "calxeda,hb-ahci"; |
| reg = <0xffe08000 0x1000>; |
| interrupts = <115>; |
| calxeda,port-phys = <&combophy5 0 &combophy0 0 &combophy0 1 |
| &combophy0 2 &combophy0 3>; |
| |
| }; |
