25  wlf,inmode:
26    description:
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)

44    description:
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.

65      unspecified inputs will use the chip default.

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.
