wlf,inmode:
description:
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) and <IN1A, IN2A, IN1B, IN2B> (wm8998, wm1814)

wlf,out-mono:
description:
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.

either MICVDD or one of the MICBIAS's, defines (ARIZONA_DMIC_xxxx)
are provided in dt-bindings/mfd/arizona.h. If present, the number
of values should be less than or equal to the number of inputs,
unspecified inputs will use the chip default.

description:
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.
