The gpio-generic driver is not appropriate here because Technologic Systems x86-based platforms do not use a typical GPIO implementation. To name a few specificities: - The GPIOs are available through ioport and not iomem - There are input-only/output-only/input-output lines on the same block - The number of GPIOs differs between blocks (currently 11, 13 and 14 pins) - A single bit in a control register drives the direction of 4 input/output lines, while the register's other bits have different functions. IMHO these considerations justify a specific GPIO driver to support these Technologic Systems pin blocks.
