Hello Nathanael,
To add configurable values for your module, you'll need to work with two
files:
./src/misc/conf.c
./src/misc/conf.h
Example patch for 0.9.24 source tree is attached. It just adds new dfbconfig
parameter, which you can simply use in your input module.
You will also need to add options for main configure script, but I guess it's
better to discuss it with one of main developers.
Also, you may find useful this post -

Patch for ELO touchscreen, attached to that post, contains example how to add
calibration paramaters as well.
