+* Qualcomm PCIe PHY controller
+
+PCIe PHY nodes are defined to describe on-chip SATA Physical layer controllers.
+Each SATA PHY controller should have its own node.
+
+- compatible:
+ Usage: required
+ Value type: <stringlist>
+ Definition: Value should contain "qcom,pcie-phy"
+
+- reg:
+ Usage: required
+ Value type: <prop-encoded-array>
+ Definition: Offset and length of the PCIe PHY registers
+
+- #phy-cells:
+ Usage: required
+ Value type: <u32>
+ Definition: Must be zero
+
+- clocks:
+ Usage: required
+ Value type: <prop-encoded-array>
+ Definition: A list of phandles and clock specifier pair, one
+ for each entry in clock-names property
+
+- clock-names:
+ Usage: required
+ Value type: <stringlist>
+ Definition: Must be "core" for PHY core clock
+
+- resets:
+ Usage: required
+ Value type: <phandle>
+ Definition: List of phandle and reset specifier pairs as listed
+ in reset-names property
+
+- reset-names:
+ Usage: required
+ Value type: <stringlist>
+ Definition: Should contain "phy" for PHY reset
+
+- <name>-supply:
+ Usage: required
+ Value type: <phandle>
+ Definition: List of phandles to the supply regulators
+ - "vdda" analog Vdd supply
+ - "vdda_pll" analog Vdd PLL supply
+
+* Example
+
+ pciephy0: phy@...26000 {
+ compatible = "qcom,pcie-phy";
+ reg = <0xfc526000 0x1000>;
+ clocks = <&gcc GCC_PCIE_0_PIPE_CLK>;
+ clock-names = "core";
+ resets = <&gcc GCC_PCIE_0_PHY_BCR>;
+ reset-names = "phy";
+ vdda-supply = <&pma8084_l3>;
+ vdda_pll-supply = <&pma8084_l12>;
+ #phy-cells = <0>;
