  1. Maxim MAX98357A audio DAC
  2. This node models the Maxim MAX98357A DAC.
  3. Required properties:
  4. - compatible : "maxim,max98357a"
  5. Optional properties:
  6. - sdmode-gpios : GPIO specifier for the chip's SD_MODE pin.
  7. If this option is not specified then driver does not manage
  8. the pin state (e.g. chip is always on).
  9. - sdmode-delay : specify delay time for SD_MODE pin.
  10. If this option is specified, which means it's required i2s clocks
  11. ready before SD_MODE is unmuted in order to avoid the speaker pop noise.
  12. It's observed that 5ms is sufficient.
  13. Example:
  14. max98357a {
  15. compatible = "maxim,max98357a";
  16. sdmode-gpios = <&qcom_pinmux 25 0>;
  17. };
