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,tas5707" - "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"; };
