3.19.8-ckt1 -stable review patch. If anyone has any objections, please let me know.
------------------
From: Pavel Machek <pavel@xxxxxx>
commit 1819e3034ee26ffadc71880064ed8b8e7d74f52c 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: Pavel Machek <pavel@xxxxxx>
[Jarkko: Headset mic bias changed to 2 (2.5 V) as it was before commit
e2e8bfdf6157 ("ASoC: tlv320aic3x: Convert mic bias to a supply widget")]
