Ok, I understand what you're saying. In fact, it seems this change, while it
allows the codec driver to automatically support all of the sample rates that
the hardware actually supports at the moment, it has the drawback in that it
doesn't tell ASoC what that list is. All .hw_params() does is accept or reject
any particular sample rate.
Is there a way for set_syclk() to tell ASoC the full list of supported rates?
That is, is there any way it can update snd_soc_dai_driver.playback.rates?
