The card works just fine with a 5.19 kernel after installing these files
in /usr/lib/firmware/ath11k/WCN6855/hw2.0/:
https://github.com/kvalo/ath11k-firmware/raw/master/WCN6855/hw2.0/1.1/WLAN.H
SP.1.1-03125-QCAHSPSWPL_V1_V2_SILICONZ_LITE-3.6510.16/amss.bin
https://github.com/kvalo/ath11k-firmware/raw/master/WCN6855/hw2.0/1.1/WLAN.
HSP.1.1-03125-QCAHSPSWPL_V1_V2_SILICONZ_LITE-3.6510.16/m3.bin
https://github.com/kvalo/ath11k-firmware/raw/master/WCN6855/hw2.0/board-2.b
in
https://github.com/kvalo/ath11k-firmware/raw/master/WCN6855/hw2.0/regdb.bin
And then creating a symlink from /usr/lib/firmware/ath11k/WCN6855/hw2.1/
to hw2.0/ .
(I do not understand the structure of the directories in
WCN6855/hw2.0/1.1/, so I choose the newest files.)
Some other firmwares from
https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git
/tree/qca are needed for Bluetooth support and are missing as well:
qca/rampatch_usb_00130201.bin
qca/nvm_usb_00130201_gf.bin
I found all the mentioned file names in the buildd log for 20220913-1, so I
guess the issue is fixed.
Can you verify that and update/close the bug accordingly?
