I was unsure about the state of iio since it recides in staging. When
can one expect it to move out of there? Has it been accepted as the
replacement for input/misc and drivers/misc sensors?

I agree that this is maybe not a long-term solution, but this is what we
have right now. Maybe not the best argument, but this can be seen as an improvement
to the bmp085 driver so "the damage has already been done".
