1* Samsung AHCI SATA Controller
2
3SATA nodes are defined to describe on-chip Serial ATA controllers.
4Each SATA controller should have its own node.
5
6Required properties:
7- compatible : compatible list, contains "samsung,exynos5-sata"
8- interrupts : <interrupt mapping for SATA IRQ>
9- reg : <registers mapping>
10- samsung,sata-freq : <frequency in MHz>
11- phys : Must contain exactly one entry as specified
12 in phy-bindings.txt
13- phy-names : Must be "sata-phy"
14
15Optional properties:
16- clocks : Must contain an entry for each entry in clock-names.
17- clock-names : Shall be "sata" for the external SATA bus clock,
18 and "sclk_sata" for the internal controller clock.

20Example:
21 sata@122f0000 {
22 compatible = "snps,dwc-ahci";
23 samsung,sata-freq = <66>;
24 reg = <0x122f0000 0x1ff>;
25 interrupts = <0 115 0>;
26 clocks = <&clock 277>, <&clock 143>;
27 clock-names = "sata", "sclk_sata";
28 phys = <&sata_phy>;
29 phy-names = "sata-phy";
30 };
