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)

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.

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.
