| Maxim MAX98357A audio DAC |
| |
| This node models the Maxim MAX98357A DAC. |
| |
| Required properties: |
| - compatible : "maxim,max98357a" |
| |
| 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>; |
| }; |
