    +Texas Instruments TAS5711/TAS5717/TAS5719 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: "ti,tas5711", "ti,tas5717", or "ti,tas5719"
    +- 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"
    +- VDD-supply: regulator phandle for the AVDD/DVDD/HP_VDD supply
    +- PVDD-supply: regulator phandle for the PVDD supply
    +
    +Example:
    +
    + tas5717: audio-codec@2a {
    + compatible = "ti,tas5717";
    + reg = <0x2a>;
    + #sound-dai-cells = <0>;
    +
    + reset-gpios = <&gpio5 1 GPIO_ACTIVE_HIGH>;
    + pdn-gpios = <&gpio5 2 GPIO_ACTIVE_HIGH>;
    +
    + clocks = <&clk_core CLK_I2S>;
    + clock-names = "mclk";
    + };
