++ 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 {

++

++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 {

++ 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";

++Ralink Fast Ethernet Embedded Switch
++====================================
++
++The ralink fast ethernet embedded switch can be found on Ralink and Mediatek
++SoCs (RT3x5x, rt5350, mt76x8).
++

++ 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>;

+Subject: [PATCH 501/513] net-next: mediatek: add the drivers core files
+
+This patch adds the main chunk of the driver. The ethernet core is used in all
+of the Mediatek/Ralink Wireless SoCs. Over the years we have seen verious
+changes to
+
+* the register layout
+* the type of ports (single/dual gbit, internal FE/Gbit switch)
+* dma engine
+
+and new offloading features were added, such as
+
+* checksum
+* vlan tx/rx
+* gso
+* lro
+
+However the core functionality has remained the sama allowing us to use the
+same core for all SoCs.
+
+The abstraction for the various SoCs uses the typical ops struct pattern which
+allows us to extend or override the cores functionality depending on which SoC
+we are on. The code to bring up the switches and external ports has also been
+split into separate files.

+Subject: [PATCH 502/513] net-next: mediatek: add switch driver for rt3050
+
+This driver is very basic and only provides basic init and irq support.
+Switchdev support for this device will follow.

+Subject: [PATCH 503/513] net-next: mediatek: add switch driver for mt7620
+
+This driver is very basic and only provides basic init and irq support.
+Switchdev support for this device will follow.

+Subject: [PATCH 504/513] net-next: mediatek: add switch driver for mt7621
+
+This driver is very basic and only provides basic init and irq support.
+Switchdev support for this device will follow.

+Subject: [PATCH 505/513] net-next: mediatek: add support for rt2880
+
+rt2880 is the oldest SoC with this core. It has a single gBit port that will
+normally be attached to an external phy of switch. The patch also adds the
+code required to drive the mdio bus.

+Subject: [PATCH 506/513] net-next: mediatek: add support for rt3050
+
+Add support for SoCs from the rt3050 family. This include rt3050, rt3052,
+rt3352 and rt5350. These all have a builtin 5 port 100mbit switch. This patch
+includes rudimentary code to power up the switch. There are a lot of magic
+values that get written to the switch and the internal phys. These values
+come straight from the SDK driver and we do not know the meaning of most of
+them.

+From: John Crispin <blogic@openwrt.org>
+Date: Mon, 14 Dec 2015 23:50:53 +0100
+Subject: [PATCH 509/513] net-next: mediatek: add support for mt7621
+
+Add support for SoCs from the mt7620 family. This include mt7620 and mt7621.
+These all have one dedicated external gbit port and a builtin 5 port 100mbit
+switch. Additionally one of the 5 switch ports can be changed to become an
+additional gbit port that we can attach a phy to. This patch includes
+rudimentary code to power up the switch. There are a lot of magic values
+that get written to the switch and the internal phys. These values come
+straight from the SDK driver.
