--説明

ドライバでは下記のように定義することが多い。

 static const char *sinkaaa_srcsel_text[] = {
 	"ValueA", "ValueB", "ValueC", //e->texts[i]
 	"ValueA", "ValueB", "ValueC",
 };
 
 static SOC_ENUM_SINGLE_DECL(sinkaaa_srcsel_enum,
 	REG_ADDR, REG_SHIFT,
 	sinkaaa_srcsel_text);
 
 static const struct snd_kcontrol_new sinkaaa_mux[] = {
 	SOC_DAPM_ENUM("SinkAAA Source", sinkaaa_srcsel_enum),
 };
 
 //これ
 static const struct snd_soc_dapm_route foo_routes[] = {
 	// sink       control   source
 	{ "SinkAAA", "ValueA", "SourceA" },
 	{ "SinkAAA", "ValueB", "SourceB" },
 	{ "SinkAAA", "ValueC", "SourceC" },
 	{ "SinkBBB", NULL, "SourceD" },
 
 	//...
 };
