-+Ralink SoC GPIO controller bindings
-+
-+Required properties:
-+- compatible:
-+ - "ralink,rt2880-gpio" for Ralink controllers
-+- #gpio-cells : Should be two.
-+ - first cell is the pin number
-+ - second cell is used to specify optional parameters (unused)
-+- gpio-controller : Marks the device node as a GPIO controller
-+- reg : Physical base address and length of the controller's registers
-+- interrupt-parent: phandle to the INTC device node
-+- interrupts : Specify the INTC interrupt number
-+- ralink,num-gpios : Specify the number of GPIOs
-+- ralink,register-map : The register layout depends on the GPIO bank and actual
-+ SoC type. Register offsets need to be in this order.
-+ [ INT, EDGE, RENA, FENA, DATA, DIR, POL, SET, RESET, TOGGLE ]
-+
-+Optional properties:
-+- ralink,gpio-base : Specify the GPIO chips base number
-+
-+Example:
-+
-+ gpio0: gpio@600 {
-+ compatible = "ralink,rt5350-gpio", "ralink,rt2880-gpio";
-+
-+ #gpio-cells = <2>;
-+ gpio-controller;
-+
-+ reg = <0x600 0x34>;
-+
-+ interrupt-parent = <&intc>;
-+ interrupts = <6>;
-+
-+ ralink,gpio-base = <0>;
-+ ralink,num-gpios = <24>;
-+ ralink,register-map = [ 00 04 08 0c
-+ 20 24 28 2c
-+ 30 34 ];

-Subject: [PATCH 2/3] phy: ralink-usb: add driver for Mediatek/Ralink
-
-Add a driver to setup the USB phy on Mediatek/Ralink SoCs.
-The driver is trivial and only sets up power and host mode.

-Subject: [PATCH] xhci: mediatek: support MTK xHCI host controller
-
-There some vendor quirks for MTK xhci host controller:
-1. It defines some extra SW scheduling parameters for HW
- to minimize the scheduling effort for synchronous and
- interrupt endpoints. The parameters are put into reseved
- DWs of slot context and endpoint context.
-2. Its IMODI unit for Interrupter Moderation register is
- 8 times as much as that defined in xHCI spec.
-3. Its TDS in Normal TRB defines a number of packets that
- remains to be transferred for a TD after processing all
- Max packets in all previous TRBs.

-+Required properties :

-+- reg: physical base address of the controller and length of memory mapped

-+- #address-cells = <1>;
-+- #size-cells = <0>;
-+
-+Optional properties:
-+- Child nodes conforming to i2c bus binding

-+
-+* Ethernet port node
-+
-+Required properties:

-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.

-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

-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.

-Subject: [PATCH 508/513] net-next: mediatek: add support for mt7620
-
-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.

-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.

-Subject: [PATCH] net: mediatek: Fix multicast ICMPv6 for the rt3050 ethernet switch.
-
-The FCT2 esw register should be set to 0x2500C to have "unknown IPv6
-multicast" packets broadcasted to every port, instead of dropped.
-The previous value only let those packets go through ports 1 and 3.
-
-"Unknown IPv6 multicast" packets include packets needed by ICMPv6 echo
-requests addressed to well-known addresses, such as ff02::1 (MAC address
-is 33:33:00:00:00:01 in this case).

-Subject: [PATCH 2/3] net: mediatek: Fix comment in rt3050 ethernet switch driver.
-
-Line 444 is actually enabling all switch ports by setting the disable bits
-to 0. This needs to be done because the bootloader sets all ports to disabled
-by default (which is the case for at least one router based on RT5350).
-
-So, this patch fixes the comment in line 443.

-Subject: [PATCH 3/3] net: mediatek: Get rt3050 ethernet ports to be disabled from the device tree.
-
-This patch allows configuring ports to be disabled in the device tree; this
-saves power, since disabling ports here actually disables power to ethernet
-PHYs.
-
-Line 444 enables all ethernet ports, so line 487 is getting zero ports to be
-disabled, except for port 5 in SoCs where this is not implemented as it will
-be sticky disabled in register POC0. Because of this, the code will still read
-the switch configuration and OR it to the device tree setting.
