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

From: Artur Weber
Date: Sat May 25 2024 - 09:28:25 EST


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.
