Kernel-4.18.0-80.el8_phy-lantiq-rcu-usb2

Lantiq XWAY SoC RCU USB 1.1/2.0 PHY binding

This binding describes the USB PHY hardware provided by the RCU module on the
Lantiq XWAY SoCs.

This node has to be a sub node of the Lantiq RCU block.

---

Required properties (controller (parent) node):

• compatible : Should be one of

        "lantiq,ase-usb2-phy"
        "lantiq,danube-usb2-phy"
        "lantiq,xrx100-usb2-phy"
        "lantiq,xrx200-usb2-phy"
        "lantiq,xrx300-usb2-phy"
  

• reg : Defines the following sets of registers in the parent

      syscon device
        - Offset of the USB PHY configuration register
        - Offset of the USB Analog configuration
          register (only for xrx200 and xrx200)
  

• clocks : References to the (PMU) “phy” clk gate.
• clock-names : Must be “phy”
• resets : References to the RCU USB configuration reset bits.
• reset-names : Must be one of the following:

        "phy" (optional)
        "ctrl" (shared)

Example for the USB PHYs on an xRX200 SoC:
usb_phy0: usb2-phy@18 {
compatible = “lantiq,xrx200-usb2-phy”;
reg = <0x18 4>, <0x38 4>;

    clocks = <&pmu PMU_GATE_USB0_PHY>;
    clock-names = "phy";
    resets = <&reset1 4 4>, <&reset0 4 4>;
    reset-names = "phy", "ctrl";
    #phy-cells = <0>;
};
