- Date: Tue, 17 Nov 2015 00:20:07 +0100
- Subject: [PATCH 500/513] Documentation: DT: net: add docs for ralink/mediatek
- SoC ethernet binding
- Add three files. ralink,rt2880-net.txt descibes the actual frame engine
- and the other two describe the switch forntend bindings.

- +Mediatek Gigabit Switch
- +=======================
- +
- +The mediatek gigabit switch can be found on Mediatek SoCs (mt7620, mt7621).
- +
- +Required properties:
- +- compatible: Should be "mediatek,mt7620-gsw"
- +- reg: Address and length of the register set for the device
- +- interrupt-parent: Should be the phandle for the interrupt controller
- + that services interrupts for this device
- +- interrupts: Should contain the gigabit switches interrupt
- +- resets: Should contain the gigabit switches resets
- +- reset-names: Should contain the reset names "gsw"
- +
- +Example:
- +
- +gsw@10110000 {
- + compatible = "ralink,mt7620-gsw";
- + reg = <0x10110000 8000>;
- +
- + resets = <&rstctrl 23>;
- + reset-names = "gsw";
- +
- + interrupt-parent = <&intc>;
- + interrupts = <17>;

- +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
- +- interrupt-parent: Should be the phandle for the interrupt controller
- + that services interrupts for this 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>;

- +Ralink Fast Ethernet Embedded Switch
- +====================================
- +
- +The ralink fast ethernet embedded switch can be found on Ralink and Mediatek
- +SoCs (RT3x5x, rt5350, mt76x8).
- +
- +Required properties:
- +- compatible: Should be "ralink,rt3050-esw"
- +- reg: Address and length of the register set for the device
- +- interrupt-parent: Should be the phandle for the interrupt controller
- + that services interrupts for this device
- +- interrupts: Should contain the embedded switches interrupt
- +- resets: Should contain the embedded switches resets
- +- reset-names: Should contain the reset names "esw"
- +
- +Optional properties:
- +- ralink,portmap: can be used to choose if the default switch setup is
- + llllw or wllll
- +- ralink,led_polarity: override the active high/low settings of the leds
- +
- +Example:
- +
- +esw@10110000 {
- + compatible = "ralink,rt3050-esw";
- + reg = <0x10110000 8000>;
- +
