I got persuaded that 3-axis accelerometers are most often indended to be
used as input devices so I decided I should take these in (adxl134x is
there). I still think that sensor devices in general are better suited
to IIO subsystem and I hope it will get out of staging soon.

Once it is out of staging we may think about creating a IIO-to-input
bridge (copuld be either in kernel or a userspace solution based on
uinput) to route sensors that are indeed used as HIDs.

Hope this makes sense.
