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.)

Yours,
Linus Walleij
