1
+
CS35L32 audio CODEC
2
+
3
+
Required properties:
4
+
5
+
- compatible : "cirrus,cs35l32"
6
+
7
+
- reg : the I2C address of the device for I2C. Address is determined by the level
8
+
of the AD0 pin. Level 0 is 0x40 while Level 1 is 0x41.
9
+
10
+
- VA-supply, VP-supply : power supplies for the device,
11
+
as covered in Documentation/devicetree/bindings/regulator/regulator.txt.
12
+
13
+
Optional properties:
14
+
15
+
- reset-gpios : a GPIO spec for the reset pin. If specified, it will be
16
+
deasserted before communication to the codec starts.
17
+
18
+
- cirrus,boost-manager : Boost voltage control.
19
+
0 = Automatically managed. Boost-converter output voltage is the higher
20
+
of the two: Class G or adaptive LED voltage.
21
+
1 = Automatically managed irrespective of audio, adapting for low-power
22
+
dissipation when LEDs are ON, and operating in Fixed-Boost Bypass Mode
23
+
if LEDs are OFF (VBST = VP).
24
+
2 = (Default) Boost voltage fixed in Bypass Mode (VBST = VP).
25
+
3 = Boost voltage fixed at 5 V.
26
+
27
+
- cirrus,sdout-datacfg : Data configuration for dual CS35L32 applications only.
28
+
Determines the data packed in a two-CS35L32 configuration.
29
+
0 = Left/right channels VMON[11:0], IMON[11:0], VPMON[7:0].
30
+
1 = Left/right channels VMON[11:0], IMON[11:0], STATUS.
31
+
2 = (Default) left/right channels VMON[15:0], IMON [15:0].
32
+
3 = Left/right channels VPMON[7:0], STATUS.
33
+
34
+
- cirrus,sdout-share : SDOUT sharing. Determines whether one or two CS35L32
35
+
devices are on board sharing SDOUT.
36
+
0 = (Default) One IC.
37
+
1 = Two IC's.
38
+
39
+
- cirrus,battery-recovery : Low battery nominal recovery threshold, rising VP.
40
+
0 = 3.1V
41
+
1 = 3.2V
42
+
2 = 3.3V (Default)
43
+
3 = 3.4V
44
+
45
+
- cirrus,battery-threshold : Low battery nominal threshold, falling VP.
46
+
0 = 3.1V
47
+
1 = 3.2V
48
+
2 = 3.3V
49
+
3 = 3.4V (Default)
50
+
4 = 3.5V
51
+
5 = 3.6V
52
+
53
+
Example:
54
+
55
+
codec: codec@40 {
56
+
compatible = "cirrus,cs35l32";
57
+
reg = <0x40>;
58
+
reset-gpios = <&gpio 10 0>;
59
+
cirrus,boost-manager = <0x03>;
60
+
cirrus,sdout-datacfg = <0x02>;
61
+
VA-supply = <®_audio>;
