Kernel-4.18.0-80.el8_cs53l30

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>;
};
