[PATCH v3 1/8] ASoC: dt-bindings: samsung,midas-audio: Add headset mic bias supply

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Some devices use a separate mic bias supply (also referred to as
"ear mic bias") to enable/disable the headset mic.

Add the DT property headset-mic-bias-supply to allow for specifying
this supply.
