22 * struct madera_codec_pdata
23 *
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.
