Moving the sample rate computation to user space sounds like the right
idea, but why not have a more drastic version of it:

Right now, all products that support this feature run at the same clock
rate (3.2 Ghz), with cpufreq, we can reduce this to 1.6 Ghz. If I understand
this correctly, the value depends only on the frequency, so we could simply
hardcode this in the kernel, and print out a warning message if we ever
encounter a different frequency, right?

Just for the record... CAB is running with 2.8 GHz. At least all the boards
I have seen.
