--------------------------------------------------

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";

	};
