* 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 string, one of:
- "allwinner,sun4i-a10-ahci"
- "fsl,imx53-ahci"
- "fsl,imx6q-ahci"
- "hisilicon,hisi-ahci"
- "ibm,476gtr-ahci"
- "marvell,armada-380-ahci"
- "snps,dwc-ahci"
- "snps,exynos5440-ahci"
- "snps,spear-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>;
};
