    gpio: Add support for Janz VMOD-TTL Digital IO module · 800e69fb
    Ira W. Snyder authored
    The Janz VMOD-TTL is a MODULbus daughterboard which fits onto any MODULbus
    carrier board. It essentially consists of some various logic and a Zilog
    Z8536 CIO Counter/Timer and Parallel IO Unit.
    
    The board must be physically configured with jumpers to enable a user to
    drive output signals. I am only interested in outputs, so I have made this
    driver as simple as possible. It only supports a very minimal subset of the
    features provided by the Z8536 chip.
