Just curious -> is'nt it better to just have min<->max range? binding as it stands right now is open to interpretation as to what will be attempted and in what sequence? with a valid min, target or max - is'nt it more power efficient always to go for a "min" than a target?
Further, min<->max implies anywhere in that range and is more consistent with "regulator like" description.
It came out after some discussions on the list, you may want to go through that.

I see the thread saying that voltage-tolerance is a crappy idea -> I agree to that.
What I dont see in the thread, and the point I raised here, why have nominal/typical voltage at all? min<->max should be sufficient, correct? If the device cannot function at min, then it should not be documented as part of valid range at all.
