CS53L30 audio CODEC
|
||
|
|
|
||
|
|
Required properties:
|
||
|
|
|
||
|
|
- compatible : "cirrus,cs53l30"
|
||
|
|
|
||
|
|
- reg : the I2C address of the device
|
||
|
|
|
||
|
|
- 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.
|
||
|
|
|
||
|
|
- mute-gpios : a GPIO spec for the MUTE pin. The active state can be either
|
||
|
|
GPIO_ACTIVE_HIGH or GPIO_ACTIVE_LOW, which would be handled
|
||
|
|
by the driver automatically.
|
||
|
|
|
||
|
|
- cirrus,micbias-lvl : Set the output voltage level on the MICBIAS Pin.
|
||
|
|
0 = Hi-Z
|
||
|
|
1 = 1.80 V
|
||
|
|
2 = 2.75 V
|
||
|
|
|
||
|
|
- cirrus,use-sdout2 : This is a boolean property. If present, it indicates
|
||
|
|
the hardware design connects both SDOUT1 and SDOUT2
|
||
|
|
pins to output data. Otherwise, it indicates that
|
||
|
|
only SDOUT1 is connected for data output.
|
||
|
|
* CS53l30 supports 4-channel data output in the same
|
||
|
|
* frame using two different ways:
|
||
|
|
* 1) Normal I2S mode on two data pins -- each SDOUT
|
||
|
|
* carries 2-channel data in the same time.
|
||
|
|
* 2) TDM mode on one signle data pin -- SDOUT1 carries
|
||
|
|
* 4-channel data per frame.
|
||
|

Example:
|
||
|
|
|
||
|
|
codec: cs53l30@48 {
|
||
|
|
compatible = "cirrus,cs53l30";
|
||
|
|
reg = <0x48>;
|
||
|
|
reset-gpios = <&gpio 54 0>;
|
||
|
|
VA-supply = <&cs53l30_va>;
|
||
|
|
VP-supply = <&cs53l30_vp>;
|
||
|
|
};
