| Subject: ARM: dts: OMAP3-N900: Add microphone bias voltages |
| |
| 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. |

| [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")] |
