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>;
};
};
