It's not long ago (about 2 years) that David Brownell (rip, my friend) introduced it to the kernel. So those should be converted to gpiolib and moved to drivers/gpio/ but it doesn't mean we don't need that piece of code. With different register layout, register offsets, register sizes, etc, it would be way uglier to combine all those into one big hacky driver. -- balbi
