from the incoming S/PDIF stream is the MCLK for the system. The CS8416 also generates SCLK and
LRCLK for the DAI side of the DSP from the recovered MCLK.
On the output side, the CS485XX slaves to MCLK from CS8416 and masters SCLK and LRCLK for the
DAC side of the CS42448.
An example of this clocking scheme can be found in pcm.cpa.
