+Cirrus Logic Arizona class audio SoCs
+
+These devices are audio SoCs with extensive digital capabilities and a range
+of analogue I/O.
+
+This document lists sound specific bindings, see the primary binding
+document:
+ ../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.
