ASoC: audio-graph-card2-custom-sample.dtsi: add Sample DT for Normal (Single)
Audio Graph Card2 settings is a little bit difficult for beginner, and Customizing it also difficult/confusable too. So, this patch adds sample for it. You can easily use it by adding below line on your DT file, and select CONFIGs to your .config. #include "../../../../../sound/soc/generic/audio-graph-card2-custom-sample.dtsi" CONFIG_SND_AUDIO_GRAPH_CARD2 CONFIG_SND_AUDIO_GRAPH_CARD2_CUSTOM_SAMPLE CONFIG_SND_TEST_COMPONENT This patch uses audio-graph-card2 base custom sample driver. You can directly use audio-graph-card2 instead of custom sample driver by modifing compatible. - compatible = "audio-graph-card2-custom-sample"; + compatible = "audio-graph-card2"; Sample custom driver will indicate customized print. It is using Test-Component driver for CPU/Codec. It can indicate more detail print of each behavior if user want to. In such case, you need to update compatible to "xxx-nv" or "xxx-vv". - compatible = "test-cpu"; + compatible = "test-cpu-verbose"; Signed-off-by: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com> Link: https://lore.kernel.org/r/87tuhmlu35.wl-kuninori.morimoto.gx@renesas.com Signed-off-by: Mark Brown <broonie@kernel.org>
