commit 1819e303 upstream. N900 audio recording needs that codec provides bias voltage for integrated digital microphone and headset microphone depending which one is used. Digital microphone uses 2 V bias and it comes from the codec A part. Codec B part drives the headset microphone bias and that is set to 2.5 V. Signed-off-by:
