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
