- Add aic3x_set_headset_detection() function to define the headset detection mode for tlv32aic3x chips - added aic3x_button_pressed() - Read from the real-time registers in aic3x_headset_detected() to query headset presence without an occured interrupt Signed-off-by: Daniel Mack <daniel@caiaq.de> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
