As mentioned on patch one, I don't think this makes sense. clock at N is
simply not correct, and if simple-bus weren't being abused it would be
far clearer that that is the case.
Please use clock_N rather than clock at N here, and get rid of the
meaningless reg values.
The simple-bus should either be removed or fixed up to meet the
requirements of the simple-bus binding (i.e. add a ranges property). I
would prefer the former.
Thanks,
Mark.
