     -----------------------
     
     Required properties:
      - compatible: rockchip,rk3399-pcie-phy
      - clocks: Must contain an entry in clock-names.
             See ../clocks/clock-bindings.txt for details.
      - clock-names: Must be "refclk"
      - resets: Must contain an entry in reset-names.
            See ../reset/reset.txt for details.
     - reset-names: Must be "phy"
    
    Required properties for legacy PHY mode (deprecated):
     - #phy-cells: must be 0
    
    Required properties for per-lane PHY mode (preferred):
     - #phy-cells: must be 1
    
    Example:
    
    grf: syscon@ff770000 {
            compatible = "rockchip,rk3399-grf", "syscon", "simple-mfd";
            #address-cells = <1>;
            #size-cells = <1>;
    
            ...
    
            pcie_phy: pcie-phy {
                    compatible = "rockchip,rk3399-pcie-phy";
                    #phy-cells = <0>;
                    clocks = <&cru SCLK_PCIEPHY_REF>;
                    clock-names = "refclk";
                    resets = <&cru SRST_PCIEPHY>;
                    reset-names = "phy";
            };
