Multiplatform for exynos is atm disabled since commit
4923ee444a39c8b75027ed01a7812e940194dbec so it'll have to wait that
upstream sort that out.

That doesn't mean there's nothing to do. For instance:

- the ucm file doesn't work with alsaucm (solved/workarounded here, see
  attached doc. I might send it upstream later) but it remains the issue
  of having something enabling or disabling the headphone output when
  plugging headphones. 

- keyboard mapping stuff so that one can get pg up/down, like what I did
  here: http://packages.rtp-net.org/debian/pool/main/x/xkeyboard-config/
  but I admit that my change suits probably only my use case... it
  doesn't solve the problem when not running Xorg.

- check if there's something to be able to adjust the brightness
  according to the light sensor (there's a device supported by the
  isl29018 driver)

There are probably other things to do and I guess that other people on
this list will be able to list them too.
