Maxim Integrated MAX98373 Speaker Amplifier
2
+
3
+
This device supports I2C.
4
+
5
+
Required properties:
6
+
7
+
- compatible : "maxim,max98373"
8
+
9
+
- reg : the I2C address of the device.
10
+
11
+
Optional properties:
12
+
13
+
- maxim,vmon-slot-no : slot number used to send voltage information
14
+
or in inteleave mode this will be used as
15
+
interleave slot.
16
+
slot range : 0 ~ 15, Default : 0
17
+
18
+
- maxim,imon-slot-no : slot number used to send current information
19
+
slot range : 0 ~ 15, Default : 0
20
+
21
+
- maxim,spkfb-slot-no : slot number used to send speaker feedback information
22
+
slot range : 0 ~ 15, Default : 0
23
+
24
+
- maxim,interleave-mode : For cases where a single combined channel
25
+
for the I/V sense data is not sufficient, the device can also be configured
26
+
to share a single data output channel on alternating frames.
27
+
In this configuration, the current and voltage data will be frame interleaved
28
+
on a single output channel.
29
+
Boolean, define to enable the interleave mode, Default : false

+
31
+
Example:
32
+
33
+
codec: max98373@31 {
34
+
compatible = "maxim,max98373";
35
+
reg = <0x31>;
36
+
maxim,vmon-slot-no = <0>;
37
+
maxim,imon-slot-no = <1>;
38
+
maxim,spkfb-slot-no = <2>;
39
+
maxim,interleave-mode;
