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";
};
