  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.
