+Samsung Exynos SoC series PCIe PHY controller
+--------------------------------------------------
+Required properties:
+- compatible : Should be set to "samsung,exynos5440-pcie-phy"
+- #phy-cells : Must be zero
+- reg : a register used by phy driver.
+ - First is for phy register, second is for block register.
+- reg-names : Must be set to "phy" and "block".
+
+Example:
+ pcie_phy0: pcie-phy@270000 {
+ #phy-cells = <0>;
+ compatible = "samsung,exynos5440-pcie-phy";
+ reg = <0x270000 0x1000>, <0x271000 0x40>;
+ reg-names = "phy", "block";
+ };
