The RTL8366S/RB switch node in DTS defines "mii-bus = <&mdio0>" to permit
management via SMI but this has likely never worked, instead falling back
to using GPIOs in the past:
rtl8366s switch: cannot find mdio bus from bus handle (yet)
rtl8366s switch: using GPIO pins 19 (SDA) and 20 (SCK)
rtl8366s switch: RTL8366 ver. 1 chip found
Recently, the rtl8366s and rtl8366_smi drivers were changed from built-in
to loadable modules. This affected driver probing order and caused switch
initialization (and network access) to fail:
rtl8366s switch: using MDIO bus 'ag71xx_mdio'
rtl8366s switch: unknown chip id (ffff)
rtl8366s switch: chip detection failed, err=-19
Force using GPIOs to manage the switch by dropping the "mii-bus" DTS
definition, which works for both built-in and loadable switch drivers.

Fixes: 575ec7a4b1 ("ath79: use rtl8366rb as a module")

This device is a wireless router working on 2.4GHz band based on
Qualcom/Atheros AR9132 rev 2 SoC and is accompanied by Atheros AR9103
wireless chip and Realtek RTL8366RB/S switches. Due to two different
switches being used also two different devices are provided.
Specification:
- 400 MHz CPU
- 64 MB of RAM
- 32 MB of FLASH (NOR)
- 3x3:2 2.4 GHz 802.11bgn
- 5x 10/100/1000 Mbps Ethernet
- 4x LED, 3x button, On/Off slider, Auto/On/Off slider
- 1x USB 2.0
- bare UART header place on PCB
Flash instruction:
- NOTE: Pay attention to the switch variant and choose the image to
flash accordingly. (dmesg / kernel logs can tell it)
- Methods for flashing
- Apply factory image in OEM firmware web-gui.
- Sysupgrade on top of existing OpenWRT image
- U-Boot TFPT recovery for both stock or OpenWRT images:
The device U-boot contains a TFTP server that by default has
an address 192.168.11.1 (MAC 02:AA:BB:CC:DD:1A). During the boot
there is a time window, during which the device allows an image to
be uploaded from a client with address 192.168.11.2. The image will
be written on flash automatically.
1) Have a computer with static IP address 192.168.11.2 and the
router device switched off.
2) Connect the LAN port next to the WAN port in the device and the
computer using a network switch.
3) Assign IP 192.168.11.1 the MAC address 02:AA:BB:CC:DD:1A
arp -s 192.168.11.1 02:AA:BB:CC:DD:1A
4) Initiate an upload using TFTP image variant
curl -T <imagename> tftp://192.168.11.1
5) Switch on the device. The image will be uploaded subsequently.
You can keep an eye on the diag light on the device, it should
keep on blinking for a while indicating the writing of the image.
General notes:
- In the stock firmware the MAC address is the same among all
interfaces so it is left here that way too.
Recovery:
- TFTP method
- U-boot serial console
Differences to ar71xx platform
- This device is split in two different targets now due to hardware
being a bit different under the hood. Dynamic solution within the same
image is left for later time.
- GPIOs for a sliding On/Off switch, marked 'Movie engine' on the device
cover, were the wrong way around and were renamed qos_on -> movie_off,
qos_off -> movie_on. Associated key codes remained the same they were.
The device tree source code is mostly based on musashino's work
