From c9d57a25de53800e54969f4bf2b672b3a58cdaf5 Mon Sep 17 00:00:00 2001 From: Trevor Wu Date: Mon, 29 Nov 2021 22:10:54 +0800 Subject: [PATCH 1/4] ASoC: mediatek: mt8195: add headset codec rt5682s support mt8195 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.

Only when adsp phandle could be retrieved from DTS, the SOF related part of machine driver is executed. Additionally, supported dai-links could be specified from DTS, so that we can disable AP side hardware controls when DSP SOF controls the same audio FE.
