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.
