From 761cab667898d86c04867948f1b7aec1090be796 Mon Sep 17 00:00:00 2001 From: Alexandre Mergnat Date: Mon, 22 Jul 2024 08:53:32 +0200 Subject: dt-bindings: mfd: mediatek: Add codec property for MT6357 PMIC Add the audio codec sub-device. This sub-device is used to set the optional voltage values according to the hardware. The properties are: - Setup of microphone bias voltage. - Setup of the speaker pin pull-down. Also, add the audio power supply property which is dedicated for the audio codec sub-device.
