-* Samsung 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 "samsung,exynos5-sata"
-- interrupts           : <interrupt mapping for SATA IRQ>
-- reg                  : <registers mapping>
-- samsung,sata-freq    : <frequency in MHz>
-- phys                 : Must contain exactly one entry as specified
-                         in phy-bindings.txt
-- phy-names            : Must be "sata-phy"
-
-Optional properties:
-- clocks               : Must contain an entry for each entry in clock-names.
-- clock-names          : Shall be "sata" for the external SATA bus clock,
-                         and "sclk_sata" for the internal controller clock.
-
-Example:
-       sata@122f0000 {
-               compatible = "snps,dwc-ahci";
-               samsung,sata-freq = <66>;
-               reg = <0x122f0000 0x1ff>;
-               interrupts = <0 115 0>;
-               clocks = <&clock 277>, <&clock 143>;
-               clock-names = "sata", "sclk_sata";
-               phys = <&sata_phy>;
-               phy-names = "sata-phy";
-       };
