Adding MAX98357A I2S DAC to a custom carrier board

Hi Kevin,

Due to the holidays I haven’t spend too much time on it, but I tried a few things:

I tried a device tree like in the post linked by Josep, or based on the following:
https://community.toradex.com/t/max98357a-on-imx7s-with-simple-audio-card/
Which for me looks like this:

	codec_ext: max98357a@0 {
		compatible = "maxim,max98357a";
		#sound-dai-cells = <0>;
	};

	sound {
		compatible = "simple-audio-card";
		simple-audio-card,name = "max98357a";
		simple-audio-card,format = "i2s";
		simple-audio-card,bitclock-master = <&dailink_master_cpu>;
		simple-audio-card,frame-master = <&dailink_master_cpu>;


		simple-audio-card,codec {
			sound-dai = <&codec_ext>;
		};


		dailink_master_cpu: simple-audio-card,cpu {
			sound-dai = <&sai1>;
		};

	};

But sadly with the same results.
