This isn't always clear - some jack detection is implemented entirely by
integrating simple components like GPIOs and ADCs or by integrating
limited support in one device with some external components to get more
features (like bolting an ADC on the side for button detect). I would
not expect to ever see a device with jack detection support that could
just be unconditionally enabled, it will always require some board level
wiring up to provide the connections required to function.
