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.
14 *
15 * #include "../../../../../sound/soc/generic/audio-graph-card2-custom-sample.dtsi"
16 *
17 * CONFIG_SND_AUDIO_GRAPH_CARD2
18 * CONFIG_SND_AUDIO_GRAPH_CARD2_CUSTOM_SAMPLE
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
24 *
25 * test_cpu {
26 * - compatible = "test-cpu";
27 * + compatible = "test-cpu-verbose";
28 * ...
29 * };
30 *
31 * test_codec {
32 * - compatible = "test-codec";
33 * + compatible = "test-codec-verbose";
34 * ...
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.
41 * see
42 * snd_soc_runtime_get_dai_fmt()
43 * linux/sound/soc/generic/test-component.c :: test_dai_formats
