I've been a little bemused about why I am getting credited for I2C bus recovery work. I don't remember doing any work on that. I did a couple of patches to fix a race when setting up a TX, but those are, afaik, unrelated. All I know about the bus recovery stuff is looking at it a while back and thinking hmm, that seems to wiggle gpio without changing the pinmuxing, so it can't possibly work. -- Jon Povey jon.povey@racelogic.co.uk Racelogic is a limited company registered in England.
