Hi Mark,
thank you for your review. I will try to solve every issue you pointed out.

Regarding non-default configurations:

This tlv320aic32x4 codec is kind of a huge monster; it has more than
200 registers which provide more flexibility than it is needed.
For example, BCLK and MCLK are forced here to derive from internal PLL
which is needed for frequency calculation table to be valid. Bypassing
this PLL doesn't provide new or better functionality.
The same happens regarding DAC internal connections. I don't think
allowing the user to swap left and right channels makes sense here.
