This is the templates for "Microphone XXX", "Line XXX", "Headphone XXX"
and "Spk XXX" .

This code has already supplied this I think.
Using this API, the only limitation is that, for example if the user has
multiple Microphones, it should set the name in DT file like:
"Mic XXX", "Mic YYY", "Mic ZZZ"...
And these widgets will use the template of : SND_SOC_DAPM_MIC("Mic", NULL),
And the widgets' names will be replaced with "Mic XXX", "Mic YYY",
"Mic ZZZ"... from the user's DT node.
Or your suggestion is ：
The templates is:
+static struct snd_soc_dapm_widget simple_widgets[] = {
+ SND_SOC_DAPM_MIC("Mic", NULL),
+ SND_SOC_DAPM_LINE("Line", NULL),
+ SND_SOC_DAPM_HP("Hp", NULL),
+ SND_SOC_DAPM_SPK("Spk", NULL),
+};
And in the DT node:
simple-off-codec-widgets =
/* template-name user-supplied-name */
"Mic", "Microphone XXX",
"Mic", "UUU Microphone YYY",
"Hp", "TTT Headphone XXX",
"Hp", "Headphone YYY";
And then just replace the template's name with the user supplied name?
