well, you can always code in both places -- i.e. have the clock
constraints set up at bind() for older (the current) platforms, and have a
different callplace in get_power() for newer platforms. This code is
anyways conditional on the hardware that is used.
I now send a patch implementing this, plus code to at runtime figure
out the effective BCLK, to the list. Please have a look at comment.
Br, Kai
