That's not the case at all for audio, the PCB schematic for the audio
subsystem on a device like a smartphone is a sufficiently interesting
piece of hardware to be a device with a driver in its own right. The
ASoC machine drivers aren't about instantiating devices, they are about
controlling the interrelationships between the various devices in the
audio subsystem.

What will happen for device tree is that there will be a device in the
device tree for the ASoC board.
