CS35L32 audio CODEC
|
|
|
|
Required properties:
|
|
|
|
- compatible : "cirrus,cs35l32"
|
|
|
|
- reg : the I2C address of the device for I2C. Address is determined by the level
|
|
of the AD0 pin. Level 0 is 0x40 while Level 1 is 0x41.
|
|
|
|
- VA-supply, VP-supply : power supplies for the device,
|
|
as covered in Documentation/devicetree/bindings/regulator/regulator.txt.
|
|
|
|
Optional properties:
|
|
|
|
- reset-gpios : a GPIO spec for the reset pin. If specified, it will be
|
|
deasserted before communication to the codec starts.
|
|
|
|
- cirrus,boost-manager : Boost voltage control.
|
|
0 = Automatically managed. Boost-converter output voltage is the higher
|
|
of the two: Class G or adaptive LED voltage.
|
|
1 = Automatically managed irrespective of audio, adapting for low-power
|
|
dissipation when LEDs are ON, and operating in Fixed-Boost Bypass Mode
|
|
if LEDs are OFF (VBST = VP).
|
|
2 = (Default) Boost voltage fixed in Bypass Mode (VBST = VP).
|
|
3 = Boost voltage fixed at 5 V.
|
|
|
|
- cirrus,sdout-datacfg : Data configuration for dual CS35L32 applications only.
|
|
Determines the data packed in a two-CS35L32 configuration.
|
|
0 = Left/right channels VMON[11:0], IMON[11:0], VPMON[7:0].
|
|
1 = Left/right channels VMON[11:0], IMON[11:0], STATUS.
|
|
2 = (Default) left/right channels VMON[15:0], IMON [15:0].
|
|
3 = Left/right channels VPMON[7:0], STATUS.
|
|
|
|
- cirrus,sdout-share : SDOUT sharing. Determines whether one or two CS35L32
|
|
devices are on board sharing SDOUT.
|
|
0 = (Default) One IC.
|
|
1 = Two IC's.
|
|
|
|
- cirrus,battery-recovery : Low battery nominal recovery threshold, rising VP.
|
|
0 = 3.1V
|
|
1 = 3.2V
|
|
2 = 3.3V (Default)
|
|
3 = 3.4V
|
|
|
|
- cirrus,battery-threshold : Low battery nominal threshold, falling VP.
|
|
0 = 3.1V
|
|
1 = 3.2V
|
|
2 = 3.3V
|
|
3 = 3.4V (Default)
|
|
4 = 3.5V
|
|
5 = 3.6V
|
|
|
|
Example:
|
|
|
|
codec: codec@40 {
|
|
compatible = "cirrus,cs35l32";
|
|
reg = <0x40>;
|
|
reset-gpios = <&gpio 10 0>;
|
|
cirrus,boost-manager = <0x03>;
|
|
cirrus,sdout-datacfg = <0x02>;
|
|
VA-supply = <®_audio>;
|
|
};
