Well, I guess this is a question for the designware maintainers: do we want this one conversion from *_relaxed to non-relaxed. Or are we playing safe by using non-relaxed all the time. I would suggest the latter because the drivers I look after hardly write registers in a hot path (and not many of them at a time). But you guys know your driver better...
