OpenWrt maintains two special out-of-tree DT properties:
"qca,disable-5ghz" and "qca,disable-2ghz". These are implemented
in a mac80211 ath9k patch "550-ath9k-disable-bands-via-dt.patch".
With the things being what they are, now might be a good
point to switch the devices to the generic and upstream
"ieee80211-freq-limit" property. This property is much
broader and works differently. Instead of disabling the
drivers logic which would add the affected band and
channels. It now disables all channels which are not
within the specified frequency range.

Atheros DB120 reference board.
Specifications:
SoC: QCA9344
DRAM: 128Mb DDR2
Flash: 8Mb SPI-NOR, 128Mb NAND flash
Switch: 5x 10/100Mbps via AR8229 switch (integrated into SoC),
5x 10/100/1000Mbps via QCA8237 via RGMII
WLAN: AR9300 (SoC, 2.4G+5G) + AR9340 (PCIe, 5G-only)
USB: 1x 2.0
UART: standard QCA UART header
JTAG: yes
Button: 1x reset
LEDs: a lot
Slots: 2x mPCIe + 1x mini-PCI, but using them requires
additional undocumented changes.
Misc: The board allows to boot off NAND, and there is
I2S audio support as well - also requiring
additional undocumented changes.
Installation:
1. Original bootloader
Connect the board to ethernet
Set up a server with an IP address of 192.168.1.10
Make the openwrt-ath79-generic-atheros_db120-squashfs-factory.bin
available via TFTP
tftpboot 0x80060000 openwrt-ath79-generic-atheros_db120-squashfs-factory.bin
erase 0x9f050000 +$filesize
cp.b $fileaddr 0x9f050000 $filesize
2. pepe2k's u-boot_mod
Connect the board to ethernet
Set up a server with an IP address of 192.168.1.10
Make the openwrt-ath79-generic-atheros_db120-squashfs-factory.bin
available via TFTP, as "firmware.bin"
run fw_upg
Reboot the board.
