* @max_channels_clocked: Maximum number of channels that I2S clocks will be
|

|
|
* generated for. Useful when clock master for systems
|
||
|
|
* where the I2S bus has multiple data lines.
|
||
|
|
* @dmic_ref: Indicates how the MICBIAS pins have been externally
|
||
|
|
* connected to DMICs on each input. A value of 0
|
||
|
|
* indicates MICVDD and is the default. Other values are:
|
||
|
|
* For CS47L35 one of the CS47L35_DMIC_REF_xxx values
|
||
|
|
* For all other codecs one of the MADERA_DMIC_REF_xxx
|
||
|
|
* Also see the datasheet for a description of the
|
||
|
|
* INn_DMIC_SUP field.
|
||
|
|
* @inmode: Mode for the ADC inputs. One of the MADERA_INMODE_xxx
|
||
|
|
* values. Two-dimensional array
|
||
|
|
* [input_number][channel number], with four slots per
|
||
|
|
* input in the order
|
||
|
|
* [n][0]=INnAL [n][1]=INnAR [n][2]=INnBL [n][3]=INnBR
|
||
|
|
* @out_mono: For each output set the value to TRUE to indicate that
|
||
|
|
* the output is mono. [0]=OUT1, [1]=OUT2, ...
|
||
|
|
* @pdm_fmt: PDM speaker data format. See the PDM_SPKn_FMT field in
|
||
|
|
* the datasheet for a description of this value.
|
||
|
|
* @pdm_mute: PDM mute format. See the PDM_SPKn_CTRL_1 register
|
||
|
|
* in the datasheet for a description of this value.
