-* 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>;
-			};
-		};
