I was more thinking along the lines of trying to avoid the unpleasant lack of control when doing this with platform data and hard-coded GPIO numbers by restricting the way it can be done in the device tree.
Hoping that there were no offenders in there already ... I guess it has to hit linux-next before we know that.
