Re: [alsa-devel] [PATCH] [v2] ASoC: support all possible sample rates in the WM8776 driver

How do you know which sysclk rate to select for a given sample rate, if you don't know the samples rates the CODEC can produces for a given sysclk rate?

You're right that supporting this feature would require the machine driver to know more about the internals of the codec. But I still think we need a better mechanism for the codec driver to tell ASoC which sample rates are actually supported.
