Hi Olivier,

It's really up to you to find something that that is missing in IIO. I'd recommend

- checking out newly released parts, preferably ones with an existing breakout
  board to make testing easier. Stores like Adafruit are great for these.
- finding an out-of-tree driver that is authored by a silicon manufacturer,
  mobile phone vendor etc. and move the driver upstream (a good example of this
  recently is a a patch series for the Sharp GP2AP070S, which has an out-of-tree
  driver in the Exynos7870 kernel tree [1])

You don't just have to add new drivers, there is a lot of code that needs cleaning
up :) I'm sure others will chime in with more ideas.
