It would work and initially I had similar patch, see [0] and related
series. Suggestion is to always use "clocks" property with devices
only.

I see. But again, I don't think it is correct to change the clock of
the codec by default. What happens if this is for example a
compatible = "fixed-clock"?

As you pointed out in the referred thread [0]. simple-audio-card has
that clock and judging from the code it is exactly for this reason:
to either change/enable it or not.

With this patch you'll switch that to "always change it". Therefore,
shouldn't there be a dt flag to indicate wheter simple-audio-card/graph
should be in charge of the codecs clock input?

And its fetching just the first clock, doesn't it? What happens if a
codec has two clock inputs?
