- 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>;
- };
