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). | |

7 | Required properties: | |

9 | - compatible: should be one of the following: |
10 | - "ti,tas5711", | |
11 | - "ti,tas5717", | |
12 | - "ti,tas5719", | |
13 | - "ti,tas5721" | |

14 | - reg: The I2C address of the device |
15 | - #sound-dai-cells: must be equal to 0 | |
