···
+* Samsung SATA PHY Controller
+
+SATA PHY nodes are defined to describe on-chip SATA Physical layer controllers.
+Each SATA PHY controller should have its own node.
+
+Required properties:
+- compatible        : compatible list, contains "samsung,exynos5-sata-phy"
+- reg               : <registers mapping>
+
+Example:
+        sata@ffe07000 {
+                compatible = "samsung,exynos5-sata-phy";
+                reg = <0xffe07000 0x1000>;
+        };

+* 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>
+
+Example:
+        sata@ffe08000 {
+                compatible = "samsung,exynos5-sata";
+                reg = <0xffe08000 0x1000>;
