This was around about the 4th IIO driver dating back to the days when I was
sticking these on sprinters and seeing if we could learn anything useful
about how they ran.
It was a device way ahead of it's time. Back then this was pretty much
the only relatively high G / low cost sensor and it had a hardware fifo.
Anyhow, it has languished in staging primarily because of the complexity
around working out how we handle hardware buffers. However, that trail has
long since been blaized by the likes of the am335x driver and now lots of
of newer devices are coming with fifos to smooth the flow of data between
these realtime chips and non realtime operating sytems, so it just became
a question of getting around to sorting it out. I suspect there are very
few of these still out there, but I have an sca3000-e05 so that's no excuse :)
Anyhow, please review the whole series, but in particular the final move
patch (i.e. the resulting code). The only odd corner I know of now is
the interaction of the watermark with the software controlled watermarks.
That may take some thought, but in the meantime I don't think that is
sufficient reason to keep it in staging.
Some wacky corners in this hardware (like the crazy number representations
for the motion detection thresholds). It's a good datasheet but you
do have to wonder what the designers were thinking at times ;)

p.s. The best bit about this series is now I can moan at everyone else
about not cleaning up their staging drivers as this is the last one
of mine ;)
