For DAPM (struct snd_soc_dapm_widget), no kind of .put() and .get() are available. I will use some Ids for the 'reg' value and use the .write() and .read() hooks available in struct snd_soc_component_driver in order to handle these Ids and so perform the accesses.

That's what the event hooks are for - there's plenty of widgets using SND_SOC_NOPM as the register, look at those for examples.

Indeed, got it. Thanks for pointing it.

Best regards, Hervé
