| 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" |
| - "ti,tas5733" |
| - 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"; |
| }; |
