I have sent the last patch of this series before, but then I realized I need to convert all users of GPIO recovery before. I needed to make sure they all set the SDA GPIO to output, this is what patches 3-5 are doing. Which is also good for them because then they can send STOP at apropriate places when doing recovery.
Then, I noticed that two drivers were not using the open drain mode for SCL which seems like a bug to me. So, patches 1+2 address that. I'd think those two are stable material.
Due to no hardware, I could only build test these patches. I'd be really looking forward to comments or tests of these patches.
A branch can be found here:

Thanks,
