- 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";
- };
