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.
19
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	};
