+* 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>;
+ };
+ };
+ };
