+Samsung Exynos SoC series PCIe PHY controller
+--------------------------------------------------
+Required properties:
+- compatible : Should be set to "samsung,exynos5433-pcie-phy"
+- #phy-cells : must be zero
+- reg : a list of registers usd by phy driver
+
+Optional properites:
+-samsung,pmureg-phandle	- handle to syscon used to control PMU registers
+-samsung,fsys-sysreg	- handle to syscon used to control the system registers
+
+Example:
+	pcie_phy: pcie-phy@15680000 {
+		#phy-cells = <0>;
+		compatible = "samsung,exynos5433-pcie-phy";
+		reg = <0x15680000 0x1000>;
+		samsung,pmureg-phandle = <&pmu_system_controller>;

+		status = "okay";
