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>; | |
62 | }; |
