+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
+
+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";
+ #phy-cells = <0>;
+ };
