25 The first cell indicating the audio interface.
30 A list of INn_MODE register values, where n is the number of input
31 signals. Valid values are 0 (Differential), 1 (Single-ended) and
32 2 (Digital Microphone). If absent, INn_MODE registers set to 0 by
33 default. If present, values must be specified less than or equal
34 to the number of input signals. If values less than the number of
35 input signals, elements that have not been specified are set to 0 by
36 default. Entries are <IN1, IN2, IN3, IN4> (wm5102, wm5110, wm8280,
37 wm8997) and <IN1A, IN2A, IN1B, IN2B> (wm8998, wm1814)

48 A list of boolean values indicating whether each output is mono
49 or stereo. Position within the list indicates the output affected
50 (eg. First entry in the list corresponds to output 1). A non-zero
51 value indicates a mono output. If present, the number of values
52 should be less than or equal to the number of outputs, if less values
53 are supplied the additional outputs will be treated as stereo.

64 DMIC reference voltage source for each input, can be selected from
65 either MICVDD or one of the MICBIAS's, defines (ARIZONA_DMIC_xxxx)
66 are provided in dt-bindings/mfd/arizona.h. If present, the number
67 of values should be less than or equal to the number of inputs,
68 unspecified inputs will use the chip default.

77 wlf,max-channels-clocked:
79 The maximum number of channels to be clocked on each AIF, useful for
80 I2S systems with multiple data lines being mastered. Specify one
81 cell for each AIF to be configured, specify zero for AIFs that should
82 be handled normally. If present, number of cells must be less than
83 or equal to the number of AIFs. If less than the number of AIFs, for
84 cells that have not been specified the corresponding AIFs will be
85 treated as default setting.

94 PDM speaker data format, must contain 2 cells (OUT5 and OUT6). See
95 the datasheet for values. The second cell is ignored for codecs that
96 do not have OUT6 (wm5102, wm8997, wm8998, wm1814)
97 $ref: /schemas/types.yaml#/definitions/uint32-array
103 PDM speaker mute setting, must contain 2 cells (OUT5 and OUT6). See
104 the datasheet for values. The second cell is ignored for codecs that
105 do not have OUT6 (wm5102, wm8997, wm8998, wm1814)
106 $ref: /schemas/types.yaml#/definitions/uint32-array
110 wlf,out-volume-limit:
112 The volume limit value that should be applied to each output
113 channel. See the datasheet for exact values. Channels are specified
114 in the order OUT1L, OUT1R, OUT2L, OUT2R, etc.
