Just to clarify, a non ASoC ALSA driver would consist of roughly the
same code, but more tightly coupled to your platform and machine
(probably consisting a single source file). ASoC basically separates out
your ALSA driver code into codec, platform and machine drivers. This
allows others to reuse your platform code with other codecs or reuse
your codec code with other platforms.

ASoC does a few other things as well (e.g. DAPM) but this is optional.
