I wrote something that suited my needs, but I kept in mind the idea of a generic layer. It's worth what it's worth, but i'm sending it in case it might help someone. Basically I nearly didn't touch the sysfs part of Robert's driver. I added the possibility to register a block of GPIO pins, and to handle interrupts. The platform specific layer registers itself with this generic layer and passes all the required platform dependant functions and parameters through a struct. Attached is the generic layer gpio.c and I moved the header in include/linux/gpio.h Feel free to comment, criticize, reject :-) Ivan
