Subject: [PATCH 07/17] ASoC: tlv320aic31xx: Add MICBIAS off setting
Date: Wed, 8 Nov 2017 18:27:31 -0600 [thread overview]
Message-ID: <20171109002741.10897-8-afd@ti.com> (raw)
In-Reply-To: <20171109002741.10897-1-afd@ti.com>
Leaving microphone bias off is a valid setting and even used in the DT
binding document example. Add this setting here and document the same.
Signed-off-by: Andrew F. Davis <afd@ti.com>
