Now, if we are back to realistic cases - use just the longest reset time.
Isn't the main concern here that when one device probes we don't yet know the times for the other devices?
If we leave things up to the drivers, then whoever probes first will get to decide the reset sequence.
In current design yes, but it's not a problem to change it. Where is the limitation? Just read other values and update the reset time.
We might have already done a reset by that time and earlier devices might prevent later devices from resetting again. It shouldn't be such an issue for the post delay, but might be one for the pre delay.
