Changes since v1:
 - Removed some description that duplicates constraints

Thanks,
Charles

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