With such an extensive list of drivers, how about putting the whole current
lot in staging whilst we figure out the eventual form?  Probably not including
the ones we already have else where, but maybe we do want them as well, so we
can merge in new features?

There is a driver for this in IIO but it exists more as an example of a trivial
driver than being fully fledged.  We've never had any interest before in doing
anything more complex with it.   I've cc'd Chris Hudson at Kionix, to comment on
what they have for these parts.

Over to Chris.

An input driver exists for that one. (cc'd Eric)

Not seen this one or the next that I can recall.

Err, naming clash ;)
Input driver has been posted... Cc'd another Eric.

> accel/lis331.c
Supported I think by the lis driver.

> accel/lsm303a.c
Not seen that one.

> accel/adxl34x.c
input driver.
> accel/lis3dh.c
also lis driver.

That is a whole host more compasses that I haven't seen drivers for. I think
we may have 2 of them in IIO...

As Manuel Stahl confirmed he also has a driver for this.
