c846dd91f0 ramips: remove model name from LED labels
Like in the previous patch for ath79 target, this will remove the
"devicename" from LED labels in ramips as well.

The devicename is removed in DTS files and 01_leds, consolidation
of definitions into DTSI files is done where (easily) possible,
and migration scripts are updated.

For the latter, all existing definitions were actually just
devicename migrations anyway. Therefore, those are removed and
a common migration file is created in target base-files. This is
actually another example of how the devicename removal makes things
easier.

621297e867 ramips: move dts-v1 statement to top-level DTSI files
The "/dts-v1/;" identifier is supposed to be present once at the
top of a device tree file after the includes have been processed.

In ramips, we therefore requested to have in the DTS files so far,
and omit it in the DTSI files. However, essentially the syntax of
the parent mtxxxx/rtxxxx DTSI files already determines the DTS
version, so putting it into the DTS files is just a useless repetition.

Consequently, this patch puts the dts-v1 statement into the top-level
SoC-based DTSI files, and removes all other occurences.
Since the dts-v1 statement needs to be before any other definitions,
this also moves the includes accordingly where necessary.

b756ea2a90 ramips: replace pinctrl property names
Upstream pinctrl driver in drivers/staging uses
groups/function/ralink,num-gpios instead of
ralink,group/ralink,function/ralink,nr-gpio
Replace these properties in dts as well as the pinctrl driver in
patches-4.14.
This commit is created using:
sed -i 's/ralink,group/groups/g'
sed -i 's/ralink,function/function/g'

2a18840cc7 ramips: add support for TP-Link RE210 v1
Hardware
--------

SoC:   MediaTek MT7620A
RAM:   64MB
FLASH: 8MB SPI
WLAN:  2G: MediaTek MT7620A
       5G: MediaTek MT7610EN
ETH:   1x 10/100/1000M (Atheros AR8035)
LED:   RSSI (orange/green)

       LED
       WPS

Serial
------

P1 - Tx
P2 - Rx
P3 - GND
P4 - VCC

Pin 4 is the one closest to the LAN port.

MAC overview
------------

WAN *:4c uboot 0x1fc00
2.4 *:4c uboot 0x1fc00
5   *:4e uboot 0x1fc00 +2

Installation
------------

Web interface:
It is possible to upgrade to OpenWrt via the web interface. However, the
OEM firmware upgrade file is required and a tool to fix the MD5 sum of
the header. This procedure overwrites U-Boot and there is not failsafe /
recovery mode present! To prepare an image, you need to take the header
and U-Boot (i.e. 0x200 + 0x20000 bytes) from an OEM firmware file and
attach the factory image to it. Then fix the header MD5Sum1.

Serial/TFTP:
You can use initramfs for booting via RAM or flash the image directly.

Additional Notes:
If the web interface upgrade fails, you have to open your device and
attach serial console. Since the web upgrade overwrites the boot loader,
you might also brick your device.

In order to flash back to stock, the first header and U-Boot needs to be
stripped from the original firmware.

1e7c6381f0 ramips: convert TP-Link MT7620 boards to tpt trigger
This converts all MediaTek MT7620 boards from TP-Link to use the now
supported WiFi throughput LED trigger. This way, the LED state now
covers all VAPs regardless of their name.

Also align all single-WiFi LEDs to represent the state of the 2.4GHz
radio. This was not always the case previously, as later-added support
for the MT7610 altered the phy probing order.

a3010a7f8d ramips: add support for TP-Link RE200 v1
TP-Link RE200 v1 is a wireless range extender with Ethernet and 2.4G and 5G
WiFi with internal antennas. It's based on MediaTek MT7620A+MT7610EN.

Specifications
--------------

- MediaTek MT7620A (580 Mhz)
- 64 MB of RAM
- 8 MB of FLASH
- 2T2R 2.4 GHz and 1T1R 5 GHz
- 1x 10/100 Mbps Ethernet
- UART header on PCB (57600 8n1)
- 8x LED (GPIO-controlled; only 6 supported), 2x button

There are 2.4G and 5G LEDs in red and green which are controlled
separately. The 5G LED is currently not supported, since the GPIOs couldn't
be determined.

Installation

Web Interface
-------------

It is possible to upgrade to OpenWrt via the web interface. However, the
OEM firmware upgrade file is required and a tool to fix the MD5 sum of
the header. This procedure overwrites U-Boot and there is not failsafe /
recovery mode present! To prepare an image, you need to take the header
and U-Boot (i.e. 0x200 + 0x20000 bytes) from an OEM firmware file and
attach the factory image to it. Then fix the header MD5Sum1.

Serial console
--------------

Opening the case is quite hard, since it is welded together. Rename the
OpenWrt factory image to "test.bin", then plug in the device and quickly
press "2" to enter flash mode (no line feed). Follow the prompts until
OpenWrt is installed.

Unfortunately, this devices does not offer a recovery mode or a tftp
installation method. If the web interface upgrade fails, you have to open
your device and attach serial console. Since the web upgrade overwrites
the boot loader, you might also brick your device.

Additional notes
----------------

MAC address assignment is based on stock-firmware. For me, the device
assigns the MAC on the label to Ethernet and the 2.4G WiFi, while the 5G
WiFi has a separate MAC with +2.

*:88    Ethernet/2.4G    label, uboot 0x1fc00, userconfig 0x0158
*:89    unused           userconfig 0x0160
*:8A    5G               not present in flash

This seems to be the first ramips device with a TP-Link v1 header. The
original firmware has the string "EU" embedded, there might be some region-
checking going on during the firmware upgrade process. The original
firmware also contains U-Boot and thus overwrites the boot loader during
upgrade.
In order to flash back to stock, the first header and U-Boot need to be
stripped from the original firmware.
