ASoC: audio-graph-card2-custom-sample2.dtsi: Separate Sample DT
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 DPCM / Codec2Codec connection part.

* 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";

|
||||
* - 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()
