These devices all acquire the multiple input lines with a single read, so utilizing the get_multiple callback can provide improvement for those users who regularly access multiple input lines. While developing this patchset I noticed many of these devices make use of Intel 8255 compatible interfaces for their I/O. I may write a generic 8255 GPIO driver in the future to reduce some of the redundant code I see pop among the drivers for these devices.
