  1. Texas Instruments TAS5711/TAS5717/TAS5719 stereo power amplifiers
  2. The codec is controlled through an I2C interface. It also has two other
  3. signals that can be wired up to GPIOs: reset (strongly recommended), and
  4. powerdown (optional).
  5. Required properties:
  6. - compatible: "ti,tas5711", "ti,tas5717", or "ti,tas5719"
  7. - reg: The I2C address of the device
  8. - #sound-dai-cells: must be equal to 0
  9. Optional properties:
  10. - reset-gpios: GPIO specifier for the TAS571x's active low reset line
  11. - pdn-gpios: GPIO specifier for the TAS571x's active low powerdown line
  12. - clocks: clock phandle for the MCLK input
  13. - clock-names: should be "mclk"
  14. - AVDD-supply: regulator phandle for the AVDD supply (all chips)
  15. - DVDD-supply: regulator phandle for the DVDD supply (all chips)
  16. - HPVDD-supply: regulator phandle for the HPVDD supply (5717/5719)
  17. - PVDD_AB-supply: regulator phandle for the PVDD_AB supply (5717/5719)
  18. - PVDD_CD-supply: regulator phandle for the PVDD_CD supply (5717/5719)
  19. - PVDD_A-supply: regulator phandle for the PVDD_A supply (5711)
  20. - PVDD_B-supply: regulator phandle for the PVDD_B supply (5711)
  21. - PVDD_C-supply: regulator phandle for the PVDD_C supply (5711)
  22. - PVDD_D-supply: regulator phandle for the PVDD_D supply (5711)
  23. Example:
  24. tas5717: audio-codec@2a {
  25. compatible = "ti,tas5717";
  26. reg = <0x2a>;
  27. #sound-dai-cells = <0>;
  28. reset-gpios = <&gpio5 1 GPIO_ACTIVE_LOW>;
  29. pdn-gpios = <&gpio5 2 GPIO_ACTIVE_LOW>;
  30. clocks = <&clk_core CLK_I2S>;
  31. clock-names = "mclk";
  32. };
