Hi all,

This series contains fixes for various issues folks have reported and
also a few not so critical improvements.

I was planning to take patches 1-3 through my fixes branch into v6.6-rc
and the patches 4 and 5 to my next branch where they can sit some more
time in linux-next until they go into v6.7.

Mika Westerberg (5):
  thunderbolt: Workaround an IOMMU fault on certain systems with Intel Maple Ridge
  thunderbolt: Check that lane 1 is in CL0 before enabling lane bonding
  thunderbolt: Correct TMU mode initialization from hardware
  thunderbolt: Apply USB 3.x bandwidth quirk only in software connection manager
  thunderbolt: Restart XDomain discovery handshake after failure

Applied these to fixes.

And decided to apply this too to fixes. I think this is pretty major
problem if someone is using Thunderbolt/USB4 peer-to-peer.

The patch 4 went into next as that's pretty cosmetic.

No need, you already provided all the necessary information on the
bugzilla! Thanks a lot for testing! :)
