-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,exynos5250-sata-phy"
-- reg : offset and length of the SATA PHY register set;
-- #phy-cells : must be zero
-- clocks : must be exactly one entry
-- clock-names : must be "sata_phyctrl"
-- samsung,exynos-sataphy-i2c-phandle : a phandle to the I2C device, no arguments
-- samsung,syscon-phandle : a phandle to the PMU system controller, no arguments
-
-Example:
-	sata_phy: sata-phy@12170000 {
-		compatible = "samsung,exynos5250-sata-phy";
-		reg = <0x12170000 0x1ff>;
-		clocks = <&clock 287>;
-		clock-names = "sata_phyctrl";
-		#phy-cells = <0>;
-		samsung,exynos-sataphy-i2c-phandle = <&sata_phy_i2c>;
-		samsung,syscon-phandle = <&pmu_syscon>;
-	};
