I'm not aware, but in linux-omap there are some non-ASoC and touchscreen
implementations for them.

Probably. E.g. in TSC2301 the touchscreen subsystem starts using audio MCLK
input whenever the audio subsystem is powered on and some internal clock
otherwise. So there can always be some undocumented subsystem dependencies.
