Code that stays into devices.[c|h] is general code that shall not be 
modified together with machine code (board-mx51_3ds.c).

Well Dmitry (linux input maintainer) asked Eric some clarifications 
before merging his work.
In all case, Eric work is going to be part of the next merge window
through the linux input tree if all goes in the right way.
So in the imx tree you would see it at least since .35

Sascha, what is your policy about this? Shall Jason support the keypad
with the current interface and update it's support in the next merge
window? or it is better to wait?

Alberto!
