Architectures like x86 that are unable or unwilling to enable the use of
the clock API are a blocker here, drivers can't make use of the API if
it's not available.  There are more architectures than x86 but it's the
only one with any active ASoC use that I'm aware of, unfortunately the
maintainers didn't react positively to attempts to enable the clock API
in the past.  I just sent a patch to try to fix it from the clock API
side so let's hope that's a bit more helpful.
