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

76 the MADERA_DMIC_REF_xxx values Also see the datasheet for a
77 description of the INn_DMIC_SUP field.

91 of zero for AIFs that should be handled normally.
