2b2abdbb75 ramips: ralink-gpio: use irqchip helpers to register driver
The gpiolib has already introduced a general GPIO irqchip framework
to initialize the GPIO irqchip[1]. This patch will make use of it
to simplify the legacy Ralink GPIO driver codes. This patch also
includes some code readability improvements.

f51cb74473 ramips: add support for Xiaomi R4AC v2 (intl)
The second edition of international version of Mi Router 4A 100M is
very similar to the non-international one, but has another wireless chip.

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

1. Initialize build-in firmware (use webgui for 192.168.31.1)
  You should install root password

2. Run OpenWRTInvasion for the first time (probably it will fail)
  Version 0.0.10 is working as well as 0.0.1.

3. Run OpenWRTInvasion for the second time
  It will create an access to your router

4. Upload sysupgrade image to router (/tmp/fw.bin)
  pc# nc -l 8080 < …/ramips/mt76x8/…-100m-intl-v2-squashfs-sysupgrade.bin
  router# nc 192.168.31.175 8080 > /tmp/fw.bin

5. Flash new firmware
  router# run mtd -r write /tmp/fw.bin OS1

6. Check result
  Wait about 5-10 minutes after flash. Router should reboot itself and
  turn left led from orange to blue.

In case of failure one can use Xiaomi 4a 100m debrick tool
(it uploads special image via tftpd in recovery mode)
After that you can start again from step 1.

Another actions are very similar to original Mi Router 4A 100M

 Original mtd paritions:
-------------------------

```
Creating 9 MTD partitions on "raspi":
0x000000000000-0x000001000000 : "ALL"
0x000000000000-0x000000020000 : "Bootloader"
0x000000020000-0x000000030000 : "Config"
0x000000030000-0x000000040000 : "Factory"
0x000000040000-0x000000050000 : "crash"
0x000000050000-0x000000060000 : "cfg_bak"
0x000000060000-0x000000160000 : "overlay"
0x000000160000-0x000000dc0000 : "OS1"
0x000000dc0000-0x000001000000 : "disk"
with special sub-partition
0x0000002c0000-0x000000dc0000 : "rootfs"
```

We will use OS1+disk space:
```
0x000000160000-0x000001000000 : "firmware"
```

Installation:
The installation must be done via TFTP by disassembling the router.
On other occasions Cudy has distributed intermediate firmware to make
installation easier, and so I recommend checking the Wiki for this
device if there is a more convenient solution than the one below.

To install using TFTP:
1. Upgrade to a beta firmware (signed by Cudy) that can be downloaded
from the wiki. This is required in order to use an unlocked u-boot.
2. Connect to UART.
3. While the router is turning on, press 1.
4. Connect to LAN and set your IP to 192.168.1.88/24. Configure a TFTP
server and an OpenWrt initramfs-kernel.bin firmware file as recovery.bin.
5. Press Enter three times. Verify the filename.
6. If you can reach LuCI or SSH now, just use the sysupgrade image with
the 'Keep settings' option turned off.

If you don't want to use the beta firmware nor the unlocked u-boot, you
can install the firmware writing the sysupgrade image on the firmware
partition of the SPI flash.

6e7bc0c243 ramips: add support for TP-Link RE205 v3
TP-Link RE205 v3 is a wireless range extender with Ethernet and 2.4G and 5G
WiFi with external antennas.
It's based on MediaTek MT7628AN+MT7610EN like the RE200 v3/v4 but with
external antennas.

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

- MediaTek MT7628AN (580 Mhz)
- 64 MB of RAM
- 8 MB of FLASH
- 2T2R 2.4 GHz and 1T1R 5 GHz
- 1x 10/100 Mbps Ethernet
- 5x LED (GPIO-controlled), 2x button
- UART connection holes on PCB (57600 8n1)

There are 2.4G and 5G LEDs in blue which are controlled separately.

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

Installation is identical to RE200 v3 devices as described at
https://openwrt.org/toh/tp-link/re200#installation

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

It is possible to upgrade to OpenWrt via the web interface. Simply flash
the -factory.bin from OEM. In contrast to a stock firmware, this will not
overwrite U-Boot.

Recovery
--------

U-Boot seems to be locked on newer versions, if not it can be accessed over
the UART as described in the link above.

fd46680966 ramips: mt76x8: enable small_flash feature
Some of devices in this target have only 8 MiB space and are closing to
borders of usable space. Particularly, TP-Link RE305 v1 already suffers
from this issue[1], where with current partition layout, on release
images, there's not enough space for overlay. So activate small_flash
feature, which will remove some userspace hardening but will gain almost
1 MiB additional flash memory space. Here is small size comparison of
similar device (RE365 v1) with default config + LuCI:

		kernel		rootfs		sysupgrade
current:	2305728		3635044		5964584
small_flash:	1713571		3320132		5047080

0709bd87ba ramips: mt76x8: add support for TP-Link RE365 v1
TP-Link RE365 is a wireless range extender, hardware-wise resembles
RE305 with slight changes regarding buttons and LEDs.

Specification
SoC: MediaTek MT7628AN
RAM: 64 MiB DDR2
Flash: 8 MiB SPI NOR
WiFi: 2.4 GHz 2T2R integrated
      5 GHz 2T2R MediaTek MT7612EN conncted to PCIe lanes
Ethernet: 1x 10/100 Mbps integrated
LEDs: 6x GPIO controlled
Buttons: 4x GPIO controlled
UART: row of 4 holes marked on PCB as J1, starting count from white
      triangle
      1. VCC (3.3V), 2. GND, 3. RX, 4. TX
      baud: 57600, parity: none, flow control: none

Installation
1. Open web management interface.
2. Go to Settings > System Tools > Firmware upgrade.
3. Select "Browse" and select the OpenWrt image with factory.bin suffix.
4. After selecting "Upgrade" firmware writing process will start.
5. Wait till device reboots, power LED should stay solid when it's fully
   booted, then it's ready for configuration through LAN port.

Additional information
With how device manufacturer patrtitioned the flash memory, it's possible
that with default packages set, initial factory.bin image won't be
created. In such case, try to reduce packages amount or use older release
for initial conversion to OpenWrt. Later You can use sysupgrade.bin
image with full set of packages because OpenWrt uses unpartitioned flash
memory space unused by vendor firmware.

Reverting to vendor firmware involves converting firmware using
tplink-safeloader with -z option (can be found in ImageBuilder or SDK)
and forcibly applying converted firmware as sysupgrade.

Known issues
WARNING: after removing casing of the device one is exposed to high
voltage and is in a risk of being electrocuted.

Caution when interfacing whith bootloader, saving its environment either
by issuing "saveenv" or selecting option "1: Load system code to SDRAM
via TFTP." in boot menu, any of those will lead to overwriting part of
kernel. This will lead to need of firmware recovery. The cause of this
issue is bootloader having environment offset on flash at 0x40000,
while kernel starts from 0x20000.

ffa40fcc7f ramips: add TP-LINK TL-WR902AC v4
Seems to be very similar to: https://openwrt.org/toh/tp-link/tl-wr902ac_v3
1 x usb
1 x eth
Powered by mini usb port.

Installation:

Can use TFTP method to install:
1. establish TFTP server at 192.168.0.66
2. provide tp_recover.bin file to the TFTP server
3. turn on router with reset button pressed
4. wait for led blinking, then release reset

Specification based on dmesg from already flashed device:

SoC Type: MediaTek MT7628AN ver:1 eco:2
CPU0 revision is: 00019655 (MIPS 24KEc)
Memory: 56028K/65536K available
CPU Clock: 580MHz
WiFi: MT7613BE

MAC addresses are all the same, except wifi5g which last part is decrement by one, ie.:

eth0		40:ed:00:cf:b9:9b
br-lan		40:ed:00:cf:b9:9b

This adds support for the TP-Link Archer C50 v6 (CA/EU/RU).
(The ES variant is a rebranded Archer C54 and NOT supported.)

CPU:   MediaTek MT7628 (580MHz)
RAM:   64M DDR2
FLASH: 8M SPI
WiFi:  2.4GHz 2x2 MT7628 b/g/n integrated

ETH:   1x WAN 4x LAN
LED:   Power, WiFi2, WiFi5, LAN, WAN, WPS
BTN:   WPS/WiFi, RESET
UART:  Near ETH ports, 115200 8n1, TP-Link pinout

Create Factory image
--------------------
As all installation methods require a U-Boot to be integrated into the
image (and we do not ship one with the image). We are not able to create
an image in the OpenWRT build-process.

Download a TP-Link image for your device variant (CA/EU or RU) from their
website and a OpenWRT sysupgrade image for the device
and build yourself a factory image like following:

TP-Link image:             tpl.bin
OpenWRT sysupgrade image:  owrt.bin

 > dd if=tpl.bin of=boot.bin bs=131584 count=1
 > cat owrt.bin >> boot.bin

Installing via Web-UI
---------------------
Upload the boot.bin via TP-Links firmware upgrade tool in the
web-interface.

Installing via Recovery
-----------------------
Activate Web-Recovery by beginning the upgrade Process with a
Firmware-Image from TP-Link. After starting the Firmware Upgrade,
wait ~3 seconds (When update status is switching to 0%), then
disconnect the power supply from the device. Upgrade flag (which
activates Web-Recovery) is written before the OS-image is touched and
removed after write is succesfull, so this procedure should be safe.

Plug the power back in. It will come up in Recovery-Mode on 192.168.0.1.
When active, all LEDs but the WPS LED are off.
Remeber to assign yourself a static IP-address as DHCP is not active in
this mode.

The boot.bin can now be uploaded and flashed using the web-recovery.

Installing via TFTP
-------------------
Prepare an image like following (Filenames from factory image steps
apply here)

 > dd if=/dev/zero of=tp_recovery.bin bs=196608 count=1
 > dd if=tpl.bin of=tmp.bin bs=131584 count=1
 > dd if=tmp.bin of=boot.bin bs=512 skip=1
 > cat boot.bin >> tp_recovery.bin
 > cat owrt.bin >> tp_recovery.bin

Place tp_recovery.bin in root directory of TFTP server and listen on
192.168.0.66/24.

Connect router LAN ports with your computer and power up the router
while pressing the reset button. The router will download the image via
tftp and after ~1 Minute reboot into OpenWRT.

U-Boot CLI
----------
U-Boot CLI can be activated by holding down '4' on bootup.

Dual U-Boot
-----------
This is the first TP-Link MediaTek device to feature a split-uboot
design. The first (factory-uboot) provides recovery via TFTP and HTTP,
jumping straight into the second (firmware-uboot) if no recovery needs
to be performed. The firmware-uboot unpacks and executed the kernel.

Web-Recovery
------------
TP-Link integrated a new Web-Recovery like the one on the Archer C7v4 /
TL-WR1043v5. Stock-firmware sets a flag in the "romfile" partition
before beginning to write and removes it afterwards. If the router boots
with this flag set, bootloader will automatically start Web-recovery and
listens on 192.168.0.1. This way, the vendor-firmware or an OpenWRT
factory image can be written.

By doing the same while performing sysupgrade, we can take advantage of
the Web-recovery in OpenWRT.

It is important to note that Web-Recovery is only based on this flag. It
can't detect e.g. a crashing kernel or other means. Once activated it
won't boot the OS before a recovery action (either via TFTP or HTTP) is
performed. This recovery-mode is indicated by an illuminated WPS-LED on
boot.

1f818b09f8 ramips: add proper system clock and reset driver support for legacy SoCs
This series of upstream patches properly implement a clock and reset
driver for old ralink SoCs[1]. And it includes some related fixes[2] and
improvements[3][4]. All patches have been merged into linux-next. They
will be part of upcoming Linux 6.5. In order to switch to the new system
controller driver, all clocks and resets properties in SoC dtsi have been
updated, and kernel symbol "CONFIG_CLK_MTMIPS" have been added to the
kernel config files.

  If it is disabled then the processor operates in LITTLE_ENDIAN mode (default),
- ARM32 - CONFIG_CPU_LITTLE_ENDIAN symbol available since kernel 5.19. This
  option should be enabled after OpenWRT moves to kernel 6.x. After refreshing
  the kernel, the symbol disappears,
- ARM64 - enabled CONFIG_CPU_LITTLE_ENDIAN,

Everything works correctly.

Currently there is no firmware update available. Because of this, in
order to restore the OEM firmware, you must firstly dump the OEM
firmware from your router before you flash the OpenWrt image.

Backup the OEM Firmware
-----------------------
The following steps are to be intended for users having little to none
experience in linux. Obviously there are many ways to backup the OEM
firmware, but probably this is the easiest way for this router.
Procedure tested on M31A3.V4300.200420 firmware version.

1) Go to http://192.168.10.1/webcmd.shtml

2) Type the following line in the "Command" input box and then press enter:
	mkdir /etc_ro/lighttpd/www/dev; cp /dev/mtd0ro /etc_ro/lighttpd/www/dev/mtd0ro; ls -la /etc_ro/lighttpd/www/dev/mtd0ro

3) After few seconds in the textarea should appear this output:
	-rw-r--r--    1 0        0         8388608 /etc_ro/lighttpd/www/dev/mtd0ro

   If your output doesn't match mine, stop reading and ask for
   help in the forum.

4) Open in another tab http://192.168.10.1/dev/mtd0ro to download the
   content of the whole NOR. If the file size is 0 byte, stop reading
   and ask for help in the forum.

5) Come back to the http://192.168.10.1/webcmd.shtml webpage and type:
	rm /etc_ro/lighttpd/www/dev/mtd0ro; for i in 1 2 3 4 ; do cp /dev/mtd${i}ro /etc_ro/lighttpd/www/dev/mtd${i}ro; done; ls -la /etc_ro/lighttpd/www/dev/

6) After few seconds, in the textarea should appear this output:
	-rw-r--r--    1 0        0          196608 mtd1ro
	-rw-r--r--    1 0        0           65536 mtd2ro
	-rw-r--r--    1 0        0           65536 mtd3ro
	-rw-r--r--    1 0        0         8060928 mtd4ro
	drwxr-xr-x    7 0        0               0 ..
	drwxr-xr-x    2 0        0               0 .

   If your output doesn't match mine, stop reading and ask for
   help in the forum.

7) Open the following links to download the partitions of the OEM FW:
	http://192.168.10.1/dev/mtd1ro
	http://192.168.10.1/dev/mtd2ro
	http://192.168.10.1/dev/mtd3ro
	http://192.168.10.1/dev/mtd4ro

   If one (or more) of these files are 0 byte, stop reading and ask
   for help in the forum.

8) Store these downloaded files in a safe place.

9) Reboot your router to remove any temporary file in ram.

Installation
------------
Flash the initramfs image in the OEM firmware interface
(http://192.168.10.1/update.shtml).
When Openwrt boots, flash the sysupgrade image otherwise you won't be
able to keep configuration between reboots.

Restore OEM Firmware
--------------------
Flash the "mtd4ro" file you previously backed-up directly from LUCI.
Warning: Remember to not keep settings!
Warning2: Remember to force the flash.

Notes
-----
1) Router mac addresses:
   LAN		XX:XX:XX:XX:XX:9B (factory @ 0x28)
   WAN		XX:XX:XX:XX:XX:9C (factory @ 0x2e)
   WIFI 2G	XX:XX:XX:XX:XX:9D (factory @ 0x04)
   WIFI 5G	XX:XX:XX:XX:XX:9E (factory @ 0x8004)

   LABEL	XX:XX:XX:XX:XX:9D

2) There is just one wifi led for both wifi interfaces.
   It currently shows only the 2.4 GHz wifi activity.
