- * This sample indicates how to use audio-graph-card2 and its
- * custom driver. "audio-graph-card2-custom-sample" is the custome driver
- * which is using audio-graph-card2.
- *
- * You can easily use this sample by adding below line on your DT file,
- * and add new CONFIG to your .config.
- *
- *	#include "../../../../../sound/soc/generic/audio-graph-card2-custom-sample.dtsi"
- *
- *	CONFIG_SND_AUDIO_GRAPH_CARD2
- *	CONFIG_SND_AUDIO_GRAPH_CARD2_CUSTOM_SAMPLE
- *	CONFIG_SND_TEST_COMPONENT
- *
- *
- * You can indicate more detail each device behavior as debug if you modify
- * "compatible" on each test-component. see below
- *
- *	test_cpu {
- *	-	compatible = "test-cpu";
- *	+	compatible = "test-cpu-verbose";
- *		...
- *	};
- *
- *	test_codec {
- *	-	compatible = "test-codec";
- *	+	compatible = "test-codec-verbose";
- *		...
- *	};
- *
- *
- * Below sample doesn't use "format" property,
- * because test-component driver (test-cpu/test-codec) is supporting
- * snd_soc_dai_ops :: .auto_selectable_formats.
- * see
- *	snd_soc_runtime_get_dai_fmt()
