These things are all sufficiently constrained by other factors - for
example, the MCLK to sample rate ratio is fixed by those two parameters
which are already known.  The Samsung CPUs aren't particularly
restrictive here as far as I remember, the fact that they implement
standard I2S helps a lot.  If you have datasheet references for any
restrictions you're concerned about please let me know.

All I'm saying is do the CPU drivers first - like I say, the main
obstacle to finishing off refreshing the CODEC driver has been having
the CPU driver to work off.  I'd expect to have something quickly given
that.  There shouldn't be much overall delay to getting the boards fully
supported.
