1*4882a593SmuzhiyunCS35L32 audio CODEC
2*4882a593Smuzhiyun
3*4882a593SmuzhiyunRequired properties:
4*4882a593Smuzhiyun
5*4882a593Smuzhiyun  - compatible : "cirrus,cs35l32"
6*4882a593Smuzhiyun
7*4882a593Smuzhiyun  - reg : the I2C address of the device for I2C. Address is determined by the level
8*4882a593Smuzhiyun  of the AD0 pin. Level 0 is 0x40 while Level 1 is 0x41.
9*4882a593Smuzhiyun
10*4882a593Smuzhiyun  - VA-supply, VP-supply : power supplies for the device,
11*4882a593Smuzhiyun  as covered in Documentation/devicetree/bindings/regulator/regulator.txt.
12*4882a593Smuzhiyun
13*4882a593SmuzhiyunOptional properties:
14*4882a593Smuzhiyun
15*4882a593Smuzhiyun  - reset-gpios : a GPIO spec for the reset pin. If specified, it will be
16*4882a593Smuzhiyun  deasserted before communication to the codec starts.
17*4882a593Smuzhiyun
18*4882a593Smuzhiyun  - cirrus,boost-manager : Boost voltage control.
19*4882a593Smuzhiyun  0 = Automatically managed.  Boost-converter output voltage is the higher
20*4882a593Smuzhiyun  of the two: Class G or adaptive LED voltage.
21*4882a593Smuzhiyun  1 = Automatically managed irrespective of audio, adapting for low-power
22*4882a593Smuzhiyun  dissipation when LEDs are ON, and operating in Fixed-Boost Bypass Mode
23*4882a593Smuzhiyun  if LEDs are OFF (VBST = VP).
24*4882a593Smuzhiyun  2 = (Default) Boost voltage fixed in Bypass Mode (VBST = VP).
25*4882a593Smuzhiyun  3 = Boost voltage fixed at 5 V.
26*4882a593Smuzhiyun
27*4882a593Smuzhiyun  - cirrus,sdout-datacfg : Data configuration for dual CS35L32 applications only.
28*4882a593Smuzhiyun  Determines the data packed in a two-CS35L32 configuration.
29*4882a593Smuzhiyun  0 = Left/right channels VMON[11:0], IMON[11:0], VPMON[7:0].
30*4882a593Smuzhiyun  1 = Left/right channels VMON[11:0], IMON[11:0], STATUS.
31*4882a593Smuzhiyun  2 = (Default) left/right channels VMON[15:0], IMON [15:0].
32*4882a593Smuzhiyun  3 = Left/right channels VPMON[7:0], STATUS.
33*4882a593Smuzhiyun
34*4882a593Smuzhiyun  - cirrus,sdout-share : SDOUT sharing. Determines whether one or two CS35L32
35*4882a593Smuzhiyun  devices are on board sharing SDOUT.
36*4882a593Smuzhiyun  0 = (Default) One IC.
37*4882a593Smuzhiyun  1 = Two IC's.
38*4882a593Smuzhiyun
39*4882a593Smuzhiyun  - cirrus,battery-recovery : Low battery nominal recovery threshold, rising VP.
40*4882a593Smuzhiyun  0 = 3.1V
41*4882a593Smuzhiyun  1 = 3.2V
42*4882a593Smuzhiyun  2 = 3.3V (Default)
43*4882a593Smuzhiyun  3 = 3.4V
44*4882a593Smuzhiyun
45*4882a593Smuzhiyun  - cirrus,battery-threshold : Low battery nominal threshold, falling VP.
46*4882a593Smuzhiyun  0 = 3.1V
47*4882a593Smuzhiyun  1 = 3.2V
48*4882a593Smuzhiyun  2 = 3.3V
49*4882a593Smuzhiyun  3 = 3.4V (Default)
50*4882a593Smuzhiyun  4 = 3.5V
51*4882a593Smuzhiyun  5 = 3.6V
