Some project use external circuit to prevent the headset ground noise. It will need to use GPIO to control it. Dell Wyse 3040 is the only project that has the external circuit so far and it uses GPIO2 for that. This patch provide the support fot it.
Mark, this seems overlooked?
No, it's complicated. IIRC it's not *actually* doing GPIO management, it's adding an option to wiggle a pin on the one board you've so far that happens to have this issue but if someone finds a GPIO from somewhere else it'll run into trouble.
How that can happen? It applies only via DMI matching.
