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>; };
