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- interrupts: Should contain the frame engines interrupt
18- resets: Should contain the frame engines resets
19- reset-names: Should contain the reset names "fe". If a switch is present
20  "esw" is also required.
21
22
23* Ethernet port node
24
25Required properties:
26- compatible: Should be "ralink,eth-port"
27- reg: The number of the physical port
28- phy-handle: reference to the node describing the phy
