Actually, on thinking about this more, the bam block itself only requires the
single clock.  The peripheral it is attached to has to keep its sanity during
the duration of the transfer (crypto).  The crypto requires 3 clocks, one of

You can access the BAM registers with the bam_clk only, correct?

Not preparing bam_clk degrades QCE performance about 3x, though.
