/**
* 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 .
