/**
 * struct madera_codec_pdata
 *
 * @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.
 * @auxpdm_slave_mode:	  Auxiliary PDM out slave mode. The value TRUE
 *			  indicates the codec is the clock slave. FALSE
 *			  means the codec is master.
 * @auxpdm_falling_edge:  Auxiliary PDM falling edge mode. The value TRUE
 *			  indicates data is driven on the falling edge of
 *			  the aux pdm clock.  FALSE means data is driven on
 *			  the rising edge.
