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.
