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 | }; | |
| 60 | ||
| 61 | }; |
