Oops, this makes more sense now. Subject even mentioned gpio, and a GPIO CS must be getting set around the transfer_one call. I'll be ready to send an r-b for a v2 with the speed update bug fixed (unless transfer speeds are guaranteed to be constant between a prepare and unprepare).
No guarantee that they'll not change, especially in a situation where we have two devices on different speeds on a bus working at the same time. -------------- next part -------------- A non-text attachment was scrubbed...
