Subject: [PATCH 396/806] ASoC: tlv320aic32x4: SND_SOC_DAPM_MICBIAS is
|
|
deprecated
|
|
|
|
commit 04d979d7a7bac2f645cd827ea37e5ffa5b4e1f97 upstream.
|
|
|
|
SND_SOC_DAPM_MICBIAS is deprecated, replace it with SND_SOC_DAPM_SUPPLY.
|
|
|
|
MICBIAS voltage wasn't supplied to the microphone with the older
|
|
SND_SOC_DAPM_MICBIAS widget, hence the microphone wouldn't work.
|
|
|
|
This patch fixes the problem.
