Ralink Frame Engine Ethernet controller ======================================= The Ralink frame engine ethernet controller can be found on Ralink and Mediatek SoCs (RT288x, RT3x5x, RT366x, RT388x, rt5350, mt7620, mt7621, mt76x8). Depending on the SoC, there is a number of ports connected to the CPU port directly and/or via a (gigabit-)switch. * Ethernet controller node Required properties: - compatible: Should be one of "ralink,rt2880-eth", "ralink,rt3050-eth", "ralink,rt3050-eth", "ralink,rt3883-eth", "ralink,rt5350-eth", "mediatek,mt7620-eth", "mediatek,mt7621-eth" - reg: Address and length of the register set for the device - interrupts: Should contain the frame engines interrupt - resets: Should contain the frame engines resets - reset-names: Should contain the reset names "fe". If a switch is present "esw" is also required. * Ethernet port node Required properties: - compatible: Should be "ralink,eth-port" - reg: The number of the physical port - phy-handle: reference to the node describing the phy Example: mdio-bus { ... phy0: ethernet-phy@0 { phy-mode = "mii"; reg = <0>; }; }; ethernet@400000 { compatible = "ralink,rt2880-eth"; reg = <0x00400000 10000>; #address-cells = <1>; #size-cells = <0>; resets = <&rstctrl 18>; reset-names = "fe"; interrupt-parent = <&cpuintc>; interrupts = <5>; port@0 { compatible = "ralink,eth-port"; reg = <0>; phy-handle = <&phy0>; }; };
