A typical embedded (or power efficient laptop) audio design will consist
of multiple devices connected together (frequently via non-control
buses) together with system level passive components and plastics which
are also important to the audio configuration.  A card binding describes
the interconections between the devices in the system and provides
identification information for the audio subsystem.  This system level
audio integration is a physical thing that can be pointed at that
requires real software control.

Like I said before please look at the existing audio card bindings.
