| 24 | * @max_channels_clocked: Maximum number of channels that I2S clocks will be
|
| 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
|
| 39 | * @out_mono: For each output set the value to TRUE to indicate that
|
| 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
|
| 44 | * in the datasheet for a description of this value.
