ok, looking around:
Just to make sure I am not running in a bad direction: Do you think
tlv320aic32x4{,-clk}.c is a good example? It is ignoring clk_id. 
I was mentally bound to have to use clk_id there, so I did not found a good
solution.

So I guess I have to configure the chip as a master and using mclk and compare
register dumps with the state we have now and the state after the changes,
additionally to check bclk functionality directly.
