Kernel-4.18.0-80.el8_pcm512x

PCM512x audio CODECs

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

Required properties:

  • compatible : One of “ti,pcm5121”, “ti,pcm5122”, “ti,pcm5141” or

             "ti,pcm5142"
    
  • reg : the I2C address of the device for I2C, the chip select

      number for SPI.
    
  • AVDD-supply, DVDD-supply, and CPVDD-supply : power supplies for the
    device, as covered in bindings/regulator/regulator.txt

Optional properties:

  • clocks : A clock specifier for the clock connected as SCLK. If this
    is absent the device will be configured to clock from BCLK. If pll-in
    and pll-out are specified in addition to a clock, the device is
    configured to accept clock input on a specified gpio pin.

  • pll-in, pll-out : gpio pins used to connect the pll using <1>
    through <6>. The device will be configured for clock input on the
    given pll-in pin and PLL output on the given pll-out pin. An
    external connection from the pll-out pin to the SCLK pin is assumed.

Examples:

pcm5122: pcm5122@4c {
    compatible = "ti,pcm5122";
    reg = <0x4c>;

    AVDD-supply = <&reg_3v3_analog>;
    DVDD-supply = <&reg_1v8>;
    CPVDD-supply = <&reg_3v3>;
};


pcm5142: pcm5142@4c {
    compatible = "ti,pcm5142";
    reg = <0x4c>;

    AVDD-supply = <&reg_3v3_analog>;
    DVDD-supply = <&reg_1v8>;
    CPVDD-supply = <&reg_3v3>;

    clocks = <&sck>;
    pll-in = <3>;
    pll-out = <6>;
};
