[PATCH v4 1/9] ASoC: dt-bindings: samsung,midas-audio: Add headset mic bias supply

Posted by Artur Weber 1 year, 4 months ago

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.
