I created SuperIO subsystem for soekris board initially. Later it was extended to support scx200/scx100 gpio (for w1 subsytem). There is support for acb(i2c) bus, GPIO, and some stub for other elements in pc8736x superIO chip. But I was told those days (about at least 1.5 years ago) in lm_sensors mail list that splitting all that functionality into separated modules is the way to go. As far as I recall pc8736x GPIO was added recently. Here is one of the implementations posted to lm_sensors@: http://archives.andrew.net.au/lm-sensors/msg27895.html And here is my drawing board with image of how it looks (just for pure interest) in my mind :) : http://tservice.net.ru/~s0mbre/old/?section=gallery&item=superio_design -- Evgeniy Polyakov
