Is there a chance that this patch can still come in the next RC?
Without this change, the board no longer starts correctly.

I think this is another kind of issue here. I had already tried to
solve the problem [1], but had not been able to follow it through to
the end.
Maybe now is the right time to tackle it again. But due to lack of

Is this yet another
75f080df46f ("Revert "clk: Detect failure to set defaults"")
kind of failure, where the clock uclass returns error code on something?
Maybe the clock uclass should rather warn than fail outright, so we
won't need these workarounds in DT files ?
