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";
};
