Since today we also got RX/TX fixed, so we have now an initial working
ath12k device with our qwz driver on OpenBSD.

What is still missing from the firmware side;  The PCI-id of the
WCN7850 chip included in the Samsung Galaxy Book4 Edge isn't included
yet in to the Linux firmware package.  I've addressed this a few times,
but unfortunately no feedback.  That's the additional PCI-id line
which is required for the Samsung Galaxy Book4 Edge:

With the resulting 'qwz-wcn7850-hw2.0-board-2' firmware board file,
we have now proved that the ath12k driver is working with Linux and
OpenBSD on the Samsung Galaxy Book4 Edge.  Maxim Storetvedt did test
with Linux.

Given that, would it be possible to include this PCI-id to the next
linux-firmware package?

Thanks and Regards,
