For example a jack that supports headsets with a button. The button could function by simply grounding one of the lines (connected to a GPIO, of course) or by generating some sort of an interrupt pulse. The jack might support other kinds of accessories as well. And the required actions and settling times might differ vastly. > If the gpio-switch framework starts > getting extended and used more, it might be sensible to convert it to > the general GPIO API, as Trilok suggested. I agree with this, but I'm afraid I don't have the time to extend the scope of my work that much right now.
