This is the big misunderstanding here. Linux is NOT a Windows in a sense of the device driver model and what the approach is used for the supported platforms. Besides that the granularity of the platform is not a *chipset*, it's *an IP*. And this makes a lot of differences here. The whatever chipset or hardware in a sense may use and re-use the same IP blocks over and over. That's why one driver can span over several generations of the hardware. This approach applies to many vendors and much more hardware IPs than just this case. I suggest you to study this more (in case you want to go deep with it).
