Kernel-4.18.0-80.el8_tas571x

Texas Instruments TAS5711/TAS5717/TAS5719/TAS5721 stereo power amplifiers

The codec is controlled through an I2C interface. It also has two other
signals that can be wired up to GPIOs: reset (strongly recommended), and
powerdown (optional).

Required properties:

• compatible: should be one of the following:
  • “ti,tas5711”,
  • “ti,tas5717”,
  • “ti,tas5719”,
  • “ti,tas5721”
• reg: The I2C address of the device
• #sound-dai-cells: must be equal to 0

Optional properties:

• reset-gpios: GPIO specifier for the TAS571x’s active low reset line
• pdn-gpios: GPIO specifier for the TAS571x’s active low powerdown line
• clocks: clock phandle for the MCLK input
• clock-names: should be “mclk”
• AVDD-supply: regulator phandle for the AVDD supply (all chips)
• DVDD-supply: regulator phandle for the DVDD supply (all chips)
• HPVDD-supply: regulator phandle for the HPVDD supply (5717/5719)
• PVDD_AB-supply: regulator phandle for the PVDD_AB supply (5717/5719)
• PVDD_CD-supply: regulator phandle for the PVDD_CD supply (5717/5719)
• PVDD_A-supply: regulator phandle for the PVDD_A supply (5711)
• PVDD_B-supply: regulator phandle for the PVDD_B supply (5711)
• PVDD_C-supply: regulator phandle for the PVDD_C supply (5711)
• PVDD_D-supply: regulator phandle for the PVDD_D supply (5711)
• DRVDD-supply: regulator phandle for the DRVDD supply (5721)
• PVDD-supply: regulator phandle for the PVDD supply (5721)

Example:

tas5717: audio-codec@2a {
    compatible = "ti,tas5717";
    reg = <0x2a>;
    #sound-dai-cells = <0>;

    reset-gpios = <&gpio5 1 GPIO_ACTIVE_LOW>;
    pdn-gpios = <&gpio5 2 GPIO_ACTIVE_LOW>;

    clocks = <&clk_core CLK_I2S>;
    clock-names = "mclk";
};
