Hi Mark & Kuninori,

For the HW I am using, there are no fixed endpoints and I am not sure if
it is allowed to have empty endpoints in audio-graph-card.
Crossbar/router provides the flexibility to connect the components in
any required order. Patch [05/23] exposes required graph and MUX
controls for the flexible configurations. Mostly, in DT, I am trying to
model the component itself and finally router can help me specify the
audio path to interconnect various components. Hence I was trying to
understand if it is really necessary to represent the links using
audio-graph-card. Kindly help me understand what more it offers. If
simple-card works fine, are we allowed to use it?

Thank you,
Sameer.
