| 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 |
