Hi!

> receivers).

Actually... I'd just call it GPS subsystem. Yes, GPS is a bit
misleading, but so is GNSS. We'd like Loran to use similar interface,
right? We'd like to QZSS to use similar interface, too...

https://www.pcworld.com/article/205325/japan_launches_its_first_gps_satelli=
te.html
=2E QZSS is not _global_ positioning system. Still they call it GPS. I'd
call it GPS too.

(Alternatively, we could have drivers/position and /dev/pos0...)

Looking closer... I'm not sure if it makes sense to push different
protocols (SiRF, NMEA, ...) through one device. Userland should know
what protocol to expect... Yes, there will be common code between
/dev/nmea0 and /dev/sirf0...

I don't know. I'd really like to see '/dev/input/event0'-like layer,
so that userland would not need to know about different protocols. But
your work solves some problems we have now...
