For embedded devices you'd normally want to do your support within the
ASoC framework. This allows the CPU, machine and codec support to be
provided separately, providing easy code reuse. There is also support
in the framework for automatic power management of the audio subsystem.
The code is in sound/soc in the kernel tree and there is some
documentation under Documentation/sound/soc.
