In my simple opinion GPSes shound live in drivers/iio/gps simply by usecase association: streaming out a series of accelerometer readings periodically through IIOs chardevs and other data about the physical world is not any different from the GPS usecase that give you a stream of coordinates on where on this planet you are. The fact that vendors like to defer GPS processing to userspace because it is considered "secret sauce" is not the concern of the kernel community, though problems like that in general is the great tragedy of our time. It would be fun to see a pure, reverse-engineered GPS driver in IIO. Just my €0.01 (And by the way: awesome work on this series.)
