Kernel-4.18.0-80.el8_rcar-gen3-phy-usb2

• Renesas R-Car generation 3 USB 2.0 PHY

This file provides information on what the device node for the R-Car generation
3 USB 2.0 PHY contains.

Required properties:

• compatible: “renesas,usb2-phy-r8a7795” if the device is a part of an R8A7795

      SoC.
      "renesas,usb2-phy-r8a7796" if the device is a part of an R8A7796
      SoC.
      "renesas,usb2-phy-r8a77965" if the device is a part of an
      R8A77965 SoC.
      "renesas,usb2-phy-r8a77995" if the device is a part of an
      R8A77995 SoC.
      "renesas,rcar-gen3-usb2-phy" for a generic R-Car Gen3 compatible device.
  
      When compatible with the generic version, nodes must list the
      SoC-specific version corresponding to the platform first
      followed by the generic version.
  

• reg: offset and length of the partial USB 2.0 Host register block.

• clocks: clock phandle and specifier pair(s).

• #phy-cells: see phy-bindings.txt in the same directory, must be <0>.

Optional properties:
To use a USB channel where USB 2.0 Host and HSUSB (USB 2.0 Peripheral) are
combined, the device tree node should set interrupt properties to use the
channel as USB OTG:

• interrupts: interrupt specifier for the PHY.
• vbus-supply: Phandle to a regulator that provides power to the VBUS. This

       regulator will be managed during the PHY power on/off sequence.
  

Example (R-Car H3):

usb-phy@ee080200 {
    compatible = "renesas,usb2-phy-r8a7795", "renesas,rcar-gen3-usb2-phy";
    reg = <0 0xee080200 0 0x700>;
    interrupts = <GIC_SPI 108 IRQ_TYPE_LEVEL_HIGH>;
    clocks = <&cpg CPG_MOD 703>;
};

usb-phy@ee0a0200 {
    compatible = "renesas,usb2-phy-r8a7795", "renesas,rcar-gen3-usb2-phy";
    reg = <0 0xee0a0200 0 0x700>;
    clocks = <&cpg CPG_MOD 702>;
};
