| * 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-sample2.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 |
