+ * This sample indicates how to use audio-graph-card2 and its

+ * 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";

+ *
+ *
+ * Below sample doesn't use "format" property,
+ * because test-component driver (test-cpu/test-codec) is supporting

audio-graph-card2-custom-sample has many sample connections, but because ALSA card has number limition for links, it is impossible to have all samples into 1 ASoC card. Separate it and took the normal connection part.
