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>; }; }; }; |
