Hey Petr,

CPU:  AR9342 SoC
RAM:      64 MB DDR2
Flash:     8 MB NOR SPI
Ports: 2x100 MBit (24V PoE in, 24V PoE out), AR8236 switch
WLAN:  2.4/5 GHz
UART:      1 UART
LEDs:        Power, 2x Ethernet, 4x RSSI LEDs (orange, red, 2x green)
Buttons:     Reset

Flashing instructions using recovery method over TFTP

  1. Unplug the ethernet cable from the router.
  2. Using paper clip press and hold the router's reset button. Make sure
     you can feel it depressed by the paper clip. Do not release the button
     until step 4.
  3. While keeping the reset button pressed in, plug the ethernet cable
     back into the AP. Keep the reset button depressed until you see the
     device's LEDs flashing in upgrade mode (alternating LED1/LED3 and
     LED2/LED4), this may take up to 25 seconds.
  4. You may release the reset button, now the device should be in TFTP
     transfer mode.
  5. Set a static IP on your Computer's NIC. A static IP of 192.168.1.25/24
     should work.
  6. Plug the PoE injector's LAN cable directly to your computer.
  7. Start tftp client and issue following commands:
      tftp> binary
      tftp> connect 192.168.1.20
      tftp> put openwrt-ath79-generic-ubnt-nano-m-xw-squashfs-factory.bin

Can't the mtd-mac-address be moved to the ar9342_ubnt_xw.dtsi? Don't weneed pll-data here?

I guess it is related to the issues in "[PATCH 2/5] ath79:ubnt-bullet-m-xw: Move common DTS bits into XW include file".

I can not find an ar71xx board which uses "nano-m-xw" as userspaceboardname. What's the purpose of adding the string to the supported devices?
