Kernel-4.18.0-80.el8_socionext,uniphier-ave4

• Socionext AVE ethernet controller

This describes the devicetree bindings for AVE ethernet controller
implemented on Socionext UniPhier SoCs.

Required properties:

• compatible: Should be
  • “socionext,uniphier-pro4-ave4” : for Pro4 SoC
  • “socionext,uniphier-pxs2-ave4” : for PXs2 SoC
  • “socionext,uniphier-ld11-ave4” : for LD11 SoC
  • “socionext,uniphier-ld20-ave4” : for LD20 SoC
  • “socionext,uniphier-pxs3-ave4” : for PXs3 SoC
• reg: Address where registers are mapped and size of region.
• interrupts: Should contain the MAC interrupt.
• phy-mode: See ethernet.txt in the same directory. Allow to choose
  “rgmii”, “rmii”, “mii”, or “internal” according to the PHY.
  The acceptable mode is SoC-dependent.
• phy-handle: Should point to the external phy device.
  See ethernet.txt file in the same directory.
• clocks: A phandle to the clock for the MAC.
  For Pro4 SoC, that is “socionext,uniphier-pro4-ave4”,
  another MAC clock, GIO bus clock and PHY clock are also required.
• clock-names: Should contain
  • “ether”, “ether-gb”, “gio”, “ether-phy” for Pro4 SoC
  • “ether” for others
• resets: A phandle to the reset control for the MAC. For Pro4 SoC,
  GIO bus reset is also required.
• reset-names: Should contain
  • “ether”, “gio” for Pro4 SoC
  • “ether” for others
• socionext,syscon-phy-mode: A phandle to syscon with one argument
  that configures phy mode. The argument is the ID of MAC instance.

Optional properties:

• local-mac-address: See ethernet.txt in the same directory.

Required subnode:

• mdio: A container for child nodes representing phy nodes.

    See phy.txt in the same directory.
  

Example:

ether: ethernet@65000000 {
    compatible = "socionext,uniphier-ld20-ave4";
    reg = <0x65000000 0x8500>;
    interrupts = <0 66 4>;
    phy-mode = "rgmii";
    phy-handle = <&ethphy>;
    clock-names = "ether";
    clocks = <&sys_clk 6>;
    reset-names = "ether";
    resets = <&sys_rst 6>;
    socionext,syscon-phy-mode = <&soc_glue 0>;
    local-mac-address = [00 00 00 00 00 00];

    mdio {
        #address-cells = <1>;
        #size-cells = <0>;

        ethphy: ethphy@1 {
            reg = <1>;
        };
    };
};
