[PATCH v7 resend 4/5] ASoC: audio-graph-card2-custom-sample: Add connection image

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Audio Graph Card2 is supporting many type of Sound connections, but
thus it is very difficult to understand how these are connected.

To support well understanding, this patch adds each connection
images and indicates each settings are for where.
