10Optional properties:
11
12  - wlf,inmode : A list of INn_MODE register values, where n is the number
13    of input signals. Valid values are 0 (Differential), 1 (Single-ended) and
14    2 (Digital Microphone). If absent, INn_MODE registers set to 0 by default.
15    If present, values must be specified less than or equal to the number of
16    input signals. If values less than the number of input signals, elements
17    that have not been specified are set to 0 by default. Entries are:
18    <IN1, IN2, IN3, IN4> (wm5102, wm5110, wm8280, wm8997)
19    <IN1A, IN2A, IN1B, IN2B> (wm8998, wm1814)
20  - wlf,out-mono : A list of boolean values indicating whether each output is
21    mono or stereo. Position within the list indicates the output affected
22    (eg. First entry in the list corresponds to output 1). A non-zero value
23    indicates a mono output. If present, the number of values should be less
24    than or equal to the number of outputs, if less values are supplied the
25    additional outputs will be treated as stereo.
26
27  - wlf,dmic-ref : DMIC reference voltage source for each input, can be
28    selected from either MICVDD or one of the MICBIAS's, defines
29    (ARIZONA_DMIC_xxxx) are provided in <dt-bindings/mfd/arizona.txt>. If
30    present, the number of values should be less than or equal to the
31    number of inputs, unspecified inputs will use the chip default.
32
33  - wlf,max-channels-clocked : The maximum number of channels to be clocked on
34    each AIF, useful for I2S systems with multiple data lines being mastered.
35    Specify one cell for each AIF to be configured, specify zero for AIFs that
36    should be handled normally.
37    If present, number of cells must be less than or equal to the number of
38    AIFs. If less than the number of AIFs, for cells that have not been
39    specified the corresponding AIFs will be treated as default setting.
40
41  - wlf,spk-fmt : PDM speaker data format, must contain 2 cells (OUT5 and OUT6).
42    See the datasheet for values.
43    The second cell is ignored for codecs that do not have OUT6 (wm5102, wm8997,
44      wm8998, wm1814)
45
46  - wlf,spk-mute : PDM speaker mute setting, must contain 2 cells (OUT5 and OUT6).
47    See the datasheet for values.
48    The second cell is ignored for codecs that do not have OUT6 (wm5102, wm8997,
49    wm8998, wm1814)
50
51  - wlf,out-volume-limit : The volume limit value that should be applied to each
52    output channel. See the datasheet for exact values. Channels are specified
53    in the order OUT1L, OUT1R, OUT2L, OUT2R, etc.
