[PATCH] ASoC: qcom: Add support for ALC5682I-VS codec

From: lvzhaoxiong
Date: Mon Nov 22 2021 - 21:43:48 EST


Qcom machine driver adds rt5682s support in this patch.
Card name can be specified from dts by model property, and driver makes
use of the name to distinguish which headset codec is on the board.
