Why This File Exists

Repeatable hardware-adapter layer. Deep compatibility for every driver is out of scope; this atlas records patterns, probe lifecycles, bus glue, IRQ/DMA usage, and links back to core abstractions.

 * 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
