The mic signal from audio jack is routed to codec A LINE1L via two switches and the mic bias is coming from codec B part. First switch is the tv-out switch that is already supported and the second switch selects between voltage detection circuit and codecs. As there is no use for voltage detection at the moment the second switch is connected statically to codecs in rx51_soc_init. Headset can be active when control "Jack Function" is set to "Headset".
