    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.
