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.
