    Subject[PATCH 0/5] gpio: Implement and utilize register structures for ISA drivers
    Date
    The PC104/ISA drivers were updated to use I/O memory accessor calls such
    as ioread8()/iowrite8() in a previous patch series [1]. This
    patchset is a continuation of the effort to improve the code readability
    and reduce magic numbers by implementing and utilizing named register
    data structures.

    One of the benefits is that we can now observe more easily similarities
    in devices that share similar interfaces; such as the i8255 interfaces
    used by the 104-DIO-48E, 104-IDI-48, and GPIO-MM drivers -- as well as
    the similar interface used by the 104-IDIO-16 and PCI-IDIO-16 drivers. I
    hope to consolidate some of these code blocks in future patchsets.
