gpio: Add support for Janz VMOD-TTL Digital IO module
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. Signed-off-by: Ira W. Snyder <iws@ovro.caltech.edu> Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>

334 This enables support for the Janz VMOD-TTL Digital IO module.
335 This driver provides support for driving the pins in output
336 mode only. Input mode is not supported.
