+* 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";
