		* 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-sample1.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()
		* linux/sound/soc/generic/test-component.c :: test_dai_formats
