1CS35L32 audio CODEC
2
3Required 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
13Optional 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
