Tell me if I'm mistaken, but doing this would implies a lot of changes.
The current wm8904 driver does not handle clk retrieval and configuration,
and I'm afraid that introducing these concepts would break other drivers 
(those
connecting to a wm8904 codec).

Do you see a simple alternative to this approach (or is there something 
I misunderstood
in your suggestion) ?

How about adding CCF support as proposed in this series and think about 
a cleaner
solution for a future release ?

Best Regards,

Boris
