I think the code is fine, my question is more about the behavior of
the hardware.  We were never able to get our board to run reliably
with the cs4270 in slave mode, so I never gave it much thought.  I was
hoping you could explain why you still need to set the mclk bits in
the mode register when you're in slave mode.
