32    description:
33      A list of input mode settings for each input. A maximum
34      of 24 cells, with four cells per input in the order INnAL,
35      INnAR INnBL INnBR.  For non-muxed inputs the first two cells
36      for that input set the mode for the left and right channel
37      and the second two cells must be 0.  For muxed inputs the
38      first two cells for that input set the mode of the left and
39      right A inputs and the second two cells set the mode of the
40      left and right B inputs.  Valid mode values are one of the
41      MADERA_INMODE_xxx. If the array is shorter than the number
42      of inputs the unspecified inputs default to MADERA_INMODE_DIFF.

73      the MADERA_DMIC_REF_xxx values Also see the datasheet for a

87      has multiple data lines.  One cell for each AIF, use a value
88      of zero for AIFs that should be handled normally.
