[PATCH v2 3/3] ASoC: mediatek: mt8188-mt6359: add SOF support
From: Trevor Wu
Date: Thu Aug 03 2023 - 01:26:40 EST
SOF is enabled when adsp phandle is assigned to "mediatek,adsp".
The required callback will be assigned when SOF is enabled.
Additionally, "mediatek,dai-link" is introduced to decide the supported
dai links for a project, so user can reuse the machine driver regardless
of dai link combination.
