17 document ../mfd/arizona.yaml
22 The first cell indicating the audio interface.
27 A list of INn_MODE register values, where n is the number of input
28 signals. Valid values are 0 (Differential), 1 (Single-ended) and
29 2 (Digital Microphone). If absent, INn_MODE registers set to 0 by
30 default. If present, values must be specified less than or equal
31 to the number of input signals. If values less than the number of
32 input signals, elements that have not been specified are set to 0 by
33 default. Entries are <IN1, IN2, IN3, IN4> (wm5102, wm5110, wm8280,
34 wm8997) and <IN1A, IN2A, IN1B, IN2B> (wm8998, wm1814)

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

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

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

91 PDM speaker data format, must contain 2 cells (OUT5 and OUT6). See
92 the datasheet for values. The second cell is ignored for codecs that
93 do not have OUT6 (wm5102, wm8997, wm8998, wm1814)

100 PDM speaker mute setting, must contain 2 cells (OUT5 and OUT6). See
101 the datasheet for values. The second cell is ignored for codecs that
102 do not have OUT6 (wm5102, wm8997, wm8998, wm1814)
103 $ref: /schemas/types.yaml#/definitions/uint32-array
107 wlf,out-volume-limit:
109 The volume limit value that should be applied to each output
110 channel. See the datasheet for exact values. Channels are specified
111 in the order OUT1L, OUT1R, OUT2L, OUT2R, etc.
