Subject: [PATCH] ASoC: mediatek: mt8183-da7219: add speaker switch
Git-commit: 514de1c935d1670e0f162210f3794cf0be67c8a7
Patch-mainline: v5.7-rc1
References: jsc#SLE-16518
Da7219 and max98357a share the same I2S lines. When writing audio data
to the I2S, both codecs generate sound.
Da7219 already has a separate control "Headphone Switch". Adds a new
control "Speakers Switch" for turning on/off max98357a. Userspace
program can decide to turn on/off which codecs by different use cases.
