    +Samsung Exynos7 soc series UFS PHY Controller
    +---------------------------------------------
    +
    +UFS PHY nodes are defined to describe on-chip UFS Physical layer controllers.
    +Each UFS PHY controller should have its own node.
    +
    +Required properties:
    +- compatible : compatible should be set to "samsung,exynos7-ufs-phy"
    +- reg : offset and length of the UFS PHY register set
    +- reg-names : reg name(s) must be 'phy-pma'
    +- #phy-cells : must be zero
    +- samsung,pmu-syscon : a phandle to the PMU system controller, no arguments
    +
    +Example:
    + ufs_phy: ufs-phy@0x15571800 {
    + compatible = "samsung,exynos7-ufs-phy";
    + reg = <0x15571800 0x240>;
    + reg-names = "phy-pma";
    + samsung,pmu-syscon = <&pmu_system_controller>;
    + #phy-cells = <0>;
    + };
