Kernel-4.18.0-80.el8_ftgmac100

  • Faraday Technology FTGMAC100 gigabit ethernet controller

Required properties:

  • compatible: “faraday,ftgmac100”

    Must also contain one of these if used as part of an Aspeed AST2400
    or 2500 family SoC as they have some subtle tweaks to the
    implementation:

    • “aspeed,ast2400-mac”
    • “aspeed,ast2500-mac”
  • reg: Address and length of the register set for the device

  • interrupts: Should contain ethernet controller interrupt

Optional properties:

  • phy-mode: See ethernet.txt file in the same directory. If the property is
    absent, “rgmii” is assumed. Supported values are “rgmii*” and “rmii” for
    aspeed parts. Other (unknown) parts will accept any value.
  • use-ncsi: Use the NC-SI stack instead of an MDIO PHY. Currently assumes
    rmii (100bT) but kept as a separate property in case NC-SI grows support
    for a gigabit link.
  • no-hw-checksum: Used to disable HW checksum support. Here for backward
    compatibility as the driver now should have correct defaults based on
    the SoC.

Example:

mac0: ethernet@1e660000 {
    compatible = "aspeed,ast2500-mac", "faraday,ftgmac100";
    reg = <0x1e660000 0x180>;
    interrupts = <2>;
    use-ncsi;
};
