In linux kernel since version 3.10 (release Date: 2013-06-30)  
Enables GPIO support for the ACCES PCIe-IDIO-24 family (PCIe-IDIO-24,
PCIe-IDI-24, PCIe-IDO-24, PCIe-IDIO-12). An interrupt is generated
when any of the inputs change state (low to high or high to low).
Input filter control is not supported by this driver, and the input
filters are deactivated by this driver.
