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.
