+This node models the Maxim MAX98357A/MAX98360A DAC.
Required properties:

+- compatible : "maxim,max98357a" for 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.
