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.
