-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>;
- };
