Maxim MAX98357A/MAX98360A audio DAC
This node models the Maxim MAX98357A/MAX98360A DAC.
Required properties:
- compatible : "maxim,max98357a" for MAX98357A.
"maxim,max98360a" for MAX98360A.
Optional properties:
- sdmode-gpios : GPIO specifier for the chip's SD_MODE pin.
If this option is not specified then driver does not manage
the pin state (e.g. chip is always on).
- sdmode-delay : specify delay time for SD_MODE pin.
If this option is specified, which means it's required i2s clocks
ready before SD_MODE is unmuted in order to avoid the speaker pop noise.
It's observed that 5ms is sufficient.
Example:
max98357a {
compatible = "maxim,max98357a";
sdmode-gpios = <&qcom_pinmux 25 0>;
};
max98360a {
compatible = "maxim,max98360a";
sdmode-gpios = <&qcom_pinmux 25 0>;
};
