For me there are two points: - Avoiding clash with kernel maintainers who hate firmware-like tables and binary data filling up the kernel. Some certain other guy bearing my name comes to mind. - Footprint: the majority of the stuff in your driver ends up in non-discardable memory, and will be kept around. Since we have this concept of a single zImage for a number of say ARMv7 systems, and since pin controllers can be pretty hard to load from modules, *all* of them may have to be compiled-in. If every driver for every board takes this approach I am afraid it will be end up with a measurable footprint.
