8 * This sample indicates how to use audio-graph-card2 and its
9 * custom driver. "audio-graph-card2-custom-sample" is the custome driver
10 * which is using audio-graph-card2.
11 *
12 * You can easily use this sample by adding below line on your DT file,
13 * and add new CONFIG to your .config.

19 *	CONFIG_SND_TEST_COMPONENT
20 *
21 *
22 * You can indicate more detail each device behavior as debug if you modify
23 * "compatible" on each test-component. see below

26 *	-	compatible = "test-cpu";

35 *	};
36 *
37 *
38 * Below sample doesn't use "format" property,
39 * because test-component driver (test-cpu/test-codec) is supporting
40 * snd_soc_dai_ops :: .auto_selectable_formats.
