Subject: [PATCH 0/4] Apple/PASemi i2c error recovery fixes
Date: Sat, 22 Feb 2025 13:38:32 +0000 [thread overview]
Message-ID: <20250222-pasemi-fixes-v1-0-d7ea33d50c5e@svenpeter.dev> (raw)
Hi,
This series adds a few fixes/improvements to the error recovery for
Apple/PASemi i2c controllers.
The patches have been in our downstream tree and were originally used
to debug a rare glitch caused by clock strechting but are useful in
general. We haven't seen the controller misbehave since adding these.
Best,
Sven
