    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@:

    And here is my drawing board with image of how it looks (just for pure
    interest) in my mind :) :
