1Ralink Frame Engine Ethernet controller
2=======================================
3
4The Ralink frame engine ethernet controller can be found on Ralink and
5Mediatek SoCs (RT288x, RT3x5x, RT366x, RT388x, rt5350, mt7620, mt7621, mt76x8).
6
7Depending on the SoC, there is a number of ports connected to the CPU port
8directly and/or via a (gigabit-)switch.
9
10* Ethernet controller node
11
12Required properties:
13- compatible: Should be one of "ralink,rt2880-eth", "ralink,rt3050-eth",
14 "ralink,rt3050-eth", "ralink,rt3883-eth", "ralink,rt5350-eth",
15 "mediatek,mt7620-eth", "mediatek,mt7621-eth"
16- reg: Address and length of the register set for the device
17- interrupt-parent: Should be the phandle for the interrupt controller
18 that services interrupts for this device
19- interrupts: Should contain the frame engines interrupt
20- resets: Should contain the frame engines resets
21- reset-names: Should contain the reset names "fe". If a switch is present
22 "esw" is also required.
23
24
25* Ethernet port node
26
27Required properties:
28- compatible: Should be "ralink,eth-port"
29- reg: The number of the physical port
30- phy-handle: reference to the node describing the phy
31

34mdio-bus {
35 ...
36 phy0: ethernet-phy@0 {
37 phy-mode = "mii";
38 reg = <0>;
39 };
40};
41
42ethernet@400000 {
43 compatible = "ralink,rt2880-eth";
44 reg = <0x00400000 10000>;
45
46 #address-cells = <1>;
47 #size-cells = <0>;
48
49 resets = <&rstctrl 18>;
50 reset-names = "fe";
51
52 interrupt-parent = <&cpuintc>;
53 interrupts = <5>;
54
55 port@0 {
56 compatible = "ralink,eth-port";
57 reg = <0>;
58 phy-handle = <&phy0>;
59 };
