   1 Ralink Frame Engine Ethernet controller
   2 =======================================
   3
   4 The Ralink frame engine ethernet controller can be found on Ralink and
   5 Mediatek SoCs (RT288x, RT3x5x, RT366x, RT388x, rt5350, mt7620, mt7621, mt76x8).
   6
   7 Depending on the SoC, there is a number of ports connected to the CPU port
   8 directly and/or via a (gigabit-)switch.
   9
  10 * Ethernet controller node
  11
  12 Required 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
  27 Required 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
  32 Example:
  33
  34 mdio-bus {
  35         ...
  36         phy0: ethernet-phy@0 {
  37                 phy-mode = "mii";
  38                 reg = <0>;
  39         };
  40 };
  41
  42 ethernet@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         };
