I don't remember doing any work on that. My mistake -- sorry.

In "i2c-davinci: Fix race when setting up for TX" and "i2c-davinci: Fix TX setup for more SoCs" you mention testing on DM355 -- is there any you have hardware on which the recovery procedure is executed on occasion and that you would be available to test modifications to the current implementation? > 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. :) Probably not then.
