Why are the system clock frequencies being specified in the DT at all - can't we either figure out the constraints from something else or just set the rates to something sensible that the driver knows (allowing for improvements in the driver in the future). > Does this sound ok? Also, would it make sense to move the pinctrl back > to the machine driver? Why would we want to do that?
