I am not aware of any Linux driver users. Furthermore, it seems there is no demand for this IC. Let's ease the maintenance burden and drop the driver. We can always add it back if there is sudden need for it.

I am not aware of any Linux driver users. Furthermore, it seems there is no demand for this IC. Ease the maintenance burden and drop the driver.
