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?
The links in the graph card should be the physical links at the edge of
the devices, those must be fixed no matter what.

I used graph-card and could get few things working with it. Based on the feedback so far, I am planning to split the series as suggested and send two series as below.
[1] Tegra AHUB series and related DT bindings as V5.
[2] Audio graph card enhancements and related DT bindings for Tegra platforms as V1.

Thanks,
Sameer.
