I did some work based on older code from some FreeBSD based work with some 
influence from OpenBSD. It uses gpio bus, gpio controller and gpio control 
primitives. Currently it works with WRAP's geode controller and another LPC 
SuperI/O GPIO controller. If you could tell me how to access your work (no 
experience with p4 tree) I will be able to integrate them together. Or I can 
use your work as an improvement. Either way, I would like to get my work put 
into official repository, but it needs some refinement.
Regards,
Milan
