Well observed; isn't this the prove of the assumption that the whole device tree idea is not working? It is *always* inconsistent and it is *maintenance hell* because out-of-tree ports do *always* breakt because of string inconsistencies. We have just ported a 8260 board from 2.6.22 to 2.6.25 and it is almost 100% oftree porting. And you do not even have a single point of a parser, because all this string parsing is completely scattered all over the tree. The ARM method of using just a device number is so much easier ...
