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"

- 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)



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";

	};
