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";
|
|
};
