As this flag is potentially dangerous, I would prefer to not apply the patch unless there is an upstream user of this. If there is one, I'd be okay with applying it with the flag renamed to something like "dangerous_push_pull_bus" or similar with additional comments saying there is some (broken) HW which needs it but nobody should get the idea to design a bus like this. Makes sense? Regards, Wolfram
