as Jonathan knows, i was one of main authors of those drivers in
drivers/staging/iio. one problem for iio is now most people still
write sensor drivers based on input subsystem or others but not iio.
and Android HAL or other frameworks prefer input _event as well.
so to push iio ahead, we might push related app ahead too.
