3.16.7-ckt12 -stable review patch. If anyone has any objections, please let me know.
------------------
From: Pavel Machek <pavel@ucw.cz>
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@ucw.cz> [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")] Signed-off-by: Jarkko Nikula <jarkko.nikula@bitmer.com> Signed-off-by: Tony Lindgren <tony@atomide.com> Signed-off-by: Luis Henriques <luis.henriques@canonical.com> --- arch/arm/boot/dts/omap3-n900.dts | 4 ++++ 1 file changed, 4 insertions(+)
