As told many times, the simple card is a pure Linux specific entity.
It does not describe any hardware. It should not appear in a DT, or,
if it does, its compatible should be "linux, simple-audio-card".
Then, how can the other OSs know the links between the audio
devices and the audio encoders/connectors?

On the other way, the audio graph does not impose any particular
software design. It just describes the links between the different
hardware components and each OS is free to implement its own layout.
