This should probably be integrated with ASoC for management of the biases if nothing else, though it'd also allow other stuff. ALSA has support for creating input devices from jacks already. > + input_set_capability(ipd, EV_SW, SW_HEADPHONE_INSERT); > + input_set_capability(ipd, EV_KEY, KEY_MEDIA); The ALSA (well, ASoC) stuff would also allow the input device to be merged with that for other detection methods so if you've got a headset jack capable of detecting other things (eg, mechanical insertion or separate mic and headphone detection). -- To unsubscribe from this list: send the line "unsubscribe linux-input" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
