Hi, This series contains the DW I2C model written by Chris Rauer and updated for the Tenstorrent Atlantis machine recently. There was some more review comment on that submission and so we decided to take the I2C device out of that series and work on it separately, see here:
https://lore.kernel.org/qemu-devel/[email protected]/T/#mb1ef2824c2f1f37bf4574dc1ef0fb95566c3a2f2 The big thing suggested was to move to the QEMU register API. That is a big change and difficult to review, so I have split that and a some smaller changes out into their own patches. I don't expect detailed reviews on the register API patch -- it's quite mechanical and I did attempt to verify it by diff'ing register traces. But it would be good to make sure maintainers are happy to go that way. Unfortunately the patch 1 was quite well reviewed and tested so incremental changes would be preferable, but it is painful to maintain migration compatibility across these changes.
