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>;
|
|
};
|
|
|
|
};
