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.

* 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.

*
|
|
* You can indicate more detail each device behavior as debug if you modify
|
|
* "compatible" on each test-component. see below

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