1 | Texas Instruments TAS5711/TAS5717/TAS5719 stereo power amplifiers |
| 2 | ||
| 3 | The codec is controlled through an I2C interface. It also has two other | |
| 4 | signals that can be wired up to GPIOs: reset (strongly recommended), and | |
| 5 | powerdown (optional). | |
| 6 | ||
| 7 | Required properties: | |
| 8 | ||
| 9 | - compatible: "ti,tas5711", "ti,tas5717", or "ti,tas5719" | |
| 10 | - reg: The I2C address of the device | |
| 11 | - #sound-dai-cells: must be equal to 0 | |
| 12 | ||
| 13 | Optional properties: | |
| 14 | ||
| 15 | - reset-gpios: GPIO specifier for the TAS571x's active low reset line | |
| 16 | - pdn-gpios: GPIO specifier for the TAS571x's active low powerdown line | |
| 17 | - clocks: clock phandle for the MCLK input | |
| 18 | - clock-names: should be "mclk" | |
| 19 | - AVDD-supply: regulator phandle for the AVDD supply (all chips) | |
| 20 | - DVDD-supply: regulator phandle for the DVDD supply (all chips) | |
| 21 | - HPVDD-supply: regulator phandle for the HPVDD supply (5717/5719) | |
| 22 | - PVDD_AB-supply: regulator phandle for the PVDD_AB supply (5717/5719) | |
| 23 | - PVDD_CD-supply: regulator phandle for the PVDD_CD supply (5717/5719) | |
| 24 | - PVDD_A-supply: regulator phandle for the PVDD_A supply (5711) | |
| 25 | - PVDD_B-supply: regulator phandle for the PVDD_B supply (5711) | |
| 26 | - PVDD_C-supply: regulator phandle for the PVDD_C supply (5711) | |
| 27 | - PVDD_D-supply: regulator phandle for the PVDD_D supply (5711) | |

| 31 | tas5717: audio-codec@2a { | |
| 32 | compatible = "ti,tas5717"; | |
| 33 | reg = <0x2a>; | |
| 34 | #sound-dai-cells = <0>; | |
| 35 | ||
| 36 | reset-gpios = <&gpio5 1 GPIO_ACTIVE_LOW>; | |
| 37 | pdn-gpios = <&gpio5 2 GPIO_ACTIVE_LOW>; | |
| 38 | ||
| 39 | clocks = <&clk_core CLK_I2S>; | |
| 40 | clock-names = "mclk"; | |
