Here is the latest mail I have on the topic.
We never got any code.
You may wish to contact the national guy,
his email is in the middle.

- Make sure it kinda/sorta works
- Make sure it meets kernel coding standards (see
Documentation/CodingStyle in any kernel)
- Make sure it has standard GPL boilerplate and your name and 
  National Semi in the comments at the top of the file so we know 
  that you and your company are really giving it away
- Write short files for the doc/ directories in i2c and/or lm_sensors
- Send it to us as a patch against the i2c-2.5.3 and/or the lm_sensors
2.5.3 tree
  (presumably you have an access.bus algorithm module for the i2c tree
and
  a 1200/1400 bus driver for the lm_sensors tree)
