Hi Fabio, I think I found a way to get our use-case working with just DTS configuration
for simple-audio-card.

When you define the “clocks” property for the "simple-audio-card,cpu” sub-node,
set_sysclk is called only once, on startup - like the IMX driver does.

We should get away without changes to the codec driver.

Thanks & best regards,
Jakob
