There's an unofficial image that's lying in a pull request on
github[1] you could use. It probably needs skip_otp parameter to be
used.

This won't work. 4.1 doesn't contain the necessary patch[2].

This looks interesting. Can you please:

 rmmod ath10k_pci
 modprobe ath10k_pci irq_mode=1

Msi range handling could be broken on this hw. If so we'll need to blacklist it.

Don't just go about renaming firmware filenames like that, please.
It's used to prevent older ath10k using newer firmware images which it
wouldn't handle anyway.

Uhm, that's wrong. Don't use cal-pci-xxx unless you know what you're doing.

fw-1 and fw-2 from dissect are otp and main program binaries.
cal-pci-xxx is just calibration data blob. This is something entirely
else.

If you see OTP failure you need to either set up adequate fw_feature
flag in the firmware-X.bin or pass skip_otp=y parameter while probing
ath10k_core module.
