Subjectcell-phone like keyboard driver anywhere?
I have to write a keyboard driver for a cell-phone like keyboard. I'm just 
wondering if this has been done before.

Basically, the keys are in some x/y matrix. How to decode that can be seen in
drivers/char/asi_keyboard.c (after applying the patches

However, this file (as any other that I have seen) assumes that there are
shift, ctrl, alt etc layers. But a cell-phone like keyboard operates
differently, e.g.

1 pause -> send keycode for character "a"
1 1 pause -> send keycode for character "b"
1 1 1 pause -> send keycode for character "c"
2 pause -> send keycode for character "d"

and so on.

Has anybody done things in this area?
