     Qualcomm PCIe2 PHY controller
     =============================
     
     The Qualcomm PCIe2 PHY is a Synopsys based phy found in a number of Qualcomm
     platforms.
     
     Required properties:
      - compatible: compatible list, should be:
                    "qcom,qcs404-pcie2-phy", "qcom,pcie2-phy"
    
     - reg: offset and length of the PHY register set.
     - #phy-cells: must be 0.
    
     - clocks: a clock-specifier pair for the "pipe" clock
    
     - vdda-vp-supply: phandle to low voltage regulator
     - vdda-vph-supply: phandle to high voltage regulator
    
     - resets: reset-specifier pairs for the "phy" and "pipe" resets
     - reset-names: list of resets, should contain:
                    "phy" and "pipe"
    
     - clock-output-names: name of the outgoing clock signal from the PHY PLL
     - #clock-cells: must be 0
    
    Example:
     phy@7786000 {
            compatible = "qcom,qcs404-pcie2-phy", "qcom,pcie2-phy";
            reg = <0x07786000 0xb8>;
    
            clocks = <&gcc GCC_PCIE_0_PIPE_CLK>;
            resets = <&gcc GCC_PCIEPHY_0_PHY_BCR>,
                     <&gcc GCC_PCIE_0_PIPE_ARES>;
            reset-names = "phy", "pipe";
    
            vdda-vp-supply = <&vreg_l3_1p05>;
            vdda-vph-supply = <&vreg_l5_1p8>;
    
            clock-output-names = "pcie_0_pipe_clk";
            #clock-cells = <0>;
            #phy-cells = <0>;
     };
