     * 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"
         - "aspeed,ast2600-mac"
    
    - reg: Address and length of the register set for the device
    - interrupts: Should contain ethernet controller interrupt
    
    Optional properties:
    - phy-handle: See ethernet.txt file in the same directory.
    - 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.
    - clocks: In accordance with the generic clock bindings. Must describe the MAC
      IP clock, and optionally an RMII RCLK gate for the AST2500/AST2600. The
      required MAC clock must be the first cell.
    - clock-names:
    
          - "MACCLK": The MAC IP clock
          - "RCLK": Clock gate for the RMII RCLK
    
    Optional subnodes:
    - mdio: See mdio.txt file in the same directory.
    
    Example:
    
            mac0: ethernet@1e660000 {
                    compatible = "aspeed,ast2500-mac", "faraday,ftgmac100";
                    reg = <0x1e660000 0x180>;
                    interrupts = <2>;
                    use-ncsi;
            };
    
    Example with phy-handle:
    
            mac1: ethernet@1e680000 {
                    compatible = "aspeed,ast2500-mac", "faraday,ftgmac100";
                    reg = <0x1e680000 0x180>;
                    interrupts = <2>;
    
                    phy-handle = <&phy>;
                    phy-mode = "rgmii";
    
                    mdio {
                            #address-cells = <1>;
                            #size-cells = <0>;
    
                            phy: ethernet-phy@1 {
                                    compatible = "ethernet-phy-ieee802.3-c22";
                                    reg = <1>;
                            };
                    };
            };
