+* Amlogic G12A USB3 + PCIE Combo PHY binding
+
+Required properties:
+- compatible: Should be "amlogic,meson-g12a-usb3-pcie-phy"
+- #phys-cells: must be 1. The cell number is used to select the phy mode
+ as defined in <dt-bindings/phy/phy.h> between PHY_TYPE_USB3 and PHY_TYPE_PCIE
+- reg: The base address and length of the registers
+- clocks: a phandle to the 100MHz reference clock of this PHY
+- clock-names: must be "ref_clk"
+- resets: phandle to the reset lines for:
+ - the PHY control
+ - the USB3+PCIE PHY
+ - the PHY registers
+
+Example:
+ usb3_pcie_phy: phy@46000 {
+ compatible = "amlogic,g12a-usb3-pcie-phy";
+ reg = <0x0 0x46000 0x0 0x2000>;
+ clocks = <&clkc CLKID_PCIE_PLL>;
+ clock-names = "ref_clk";
+ resets = <&reset RESET_PCIE_CTRL_A>,
+ <&reset RESET_PCIE_PHY>,
+ <&reset RESET_PCIE_APB>;
+ #phy-cells = <1>;
+ };
