Hi Kalle,

  Thanks for the latest tag!  I've built and booted it successfully a
number of times.  The wifi connection has remained stable and seems to
be behaving nominally.  I'll update here as I get some more testing
in.

tag: ath11k-qca6390-bringup-202012140938 , no other changes
hw: dell xps 9310 (13")

  ps - I did notice a crash from the btqca driver I didn't see before,
but I'm not sure that's new.
