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>;
|
|

|
|

|
|
+ interrupt-parent = <&cpuintc>;
|
|
+ interrupts = <5>;

+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>;
|
