| * 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, one of "snps,spear-ahci", |
| "snps,exynos5440-ahci", "ibm,476gtr-ahci", |
| "allwinner,sun4i-a10-ahci", "fsl,imx53-ahci" |
| "fsl,imx6q-ahci" or "snps,dwc-ahci" |
| - interrupts : <interrupt mapping for SATA IRQ> |
| - reg : <registers mapping> |
| |
| Optional properties: |
| - dma-coherent : Present if dma operations are coherent |
| - clocks : a list of phandle + clock specifier pairs |
| - target-supply : regulator for SATA target power |
| |
| "fsl,imx53-ahci", "fsl,imx6q-ahci" required properties: |
| - clocks : must contain the sata, sata_ref and ahb clocks |
| - clock-names : must contain "ahb" for the ahb clock |
| |
| Examples: |
| sata@ffe08000 { |
| compatible = "snps,spear-ahci"; |
| reg = <0xffe08000 0x1000>; |
| interrupts = <115>; |
| }; |
| |
| ahci: sata@01c18000 { |
| compatible = "allwinner,sun4i-a10-ahci"; |
| reg = <0x01c18000 0x1000>; |
| interrupts = <56>; |
| clocks = <&pll6 0>, <&ahb_gates 25>; |
| target-supply = <®_ahci_5v>; |
| }; |
