Kernel-4.18.0-80.el8_pcm186x

Texas Instruments PCM186x Universal Audio ADC

These devices support both I2C and SPI (configured with pin strapping
on the board).

Required properties:

• compatible : “ti,pcm1862”,

           "ti,pcm1863",
           "ti,pcm1864",
           "ti,pcm1865"
  

• reg : The I2C address of the device for I2C, the chip select

    number for SPI.
  

• avdd-supply: Analog core power supply (3.3v)

• dvdd-supply: Digital core power supply

• iovdd-supply: Digital IO power supply

   See regulator/regulator.txt for more information
  

CODEC input pins:

• VINL1
• VINR1
• VINL2
• VINR2
• VINL3
• VINR3
• VINL4
• VINR4

The pins can be used in referring sound node’s audio-routing property.

Example:

pcm186x: audio-codec@4a {
    compatible = "ti,pcm1865";
    reg = <0x4a>;

    avdd-supply = <&reg_3v3_analog>;
    dvdd-supply = <&reg_3v3>;
    iovdd-supply = <&reg_1v8>;
};
