1Maxim MAX98357A/MAX98360A audio DAC 2 3This node models the Maxim MAX98357A/MAX98360A DAC. 4 5Required properties: 6- compatible : "maxim,max98357a" for MAX98357A. 7 "maxim,max98360a" for MAX98360A. 8 9Optional properties: 10- sdmode-gpios : GPIO specifier for the chip's SD_MODE pin. 11 If this option is not specified then driver does not manage 12 the pin state (e.g. chip is always on). 13- sdmode-delay : specify delay time for SD_MODE pin. 14 If this option is specified, which means it's required i2s clocks 15 ready before SD_MODE is unmuted in order to avoid the speaker pop noise. 16 It's observed that 5ms is sufficient. 17 18Example: 19 20max98357a { 21 compatible = "maxim,max98357a"; 22 sdmode-gpios = <&qcom_pinmux 25 0>; 23}; 24 25max98360a { 26 compatible = "maxim,max98360a"; 27 sdmode-gpios = <&qcom_pinmux 25 0>; 28};
