[PATCH 4/4] ASoC: mediatek: mt8195: add machine driver for MT8195 SOF support
From: Trevor Wu
Date: Wed Nov 03 2021 - 06:00:59 EST
This patch adds SOF support for mt8195 board with mt6359, rt1019 and
rt5682.
We define connection table "sof_conn_stream" and add route path to
connect SOF driver path to backend of normal platform in the late
probe callback.
