Assuming I understand you correctly, the problem still remains of having the
S/PDIF driver to setup clock hierarchies -- which is the job of the
board init code, IMHO.
So until we have proper clock subsystem and board init code to handle
such scenarios
we have to do that in ASoC machine driver in such hackish way.
