| 25 | * generated for. Useful when clock master for systems |
|---|
| 26 | * where the I2S bus has multiple data lines. |
|---|
| 27 | * @dmic_ref: Indicates how the MICBIAS pins have been externally |
|---|
| 28 | * connected to DMICs on each input. A value of 0 |
|---|
| 29 | * indicates MICVDD and is the default. Other values are: |
|---|
| 30 | * For CS47L35 one of the CS47L35_DMIC_REF_xxx values |
|---|
| 31 | * For all other codecs one of the MADERA_DMIC_REF_xxx |

| 32 | * Also see the datasheet for a description of the |

| 33 | * INn_DMIC_SUP field. |
|---|
| 34 | * @inmode: Mode for the ADC inputs. One of the MADERA_INMODE_xxx |
|---|
| 35 | * values. Two-dimensional array |
|---|
| 36 | * [input_number][channel number], with four slots per |
|---|
| 37 | * input in the order |
|---|
| 38 | * [n][0]=INnAL [n][1]=INnAR [n][2]=INnBL [n][3]=INnBR |

|---|
| 40 | * the output is mono. [0]=OUT1, [1]=OUT2, ... |
|---|
| 41 | * @pdm_fmt: PDM speaker data format. See the PDM_SPKn_FMT field in |
|---|
| 42 | * the datasheet for a description of this value. |
|---|
| 43 | * @pdm_mute: PDM mute format. See the PDM_SPKn_CTRL_1 register |
