I am writing an ASoC driver, where i can place these calls

In soc-core.c ?

I suppose so. In soc_suspend() and soc_resume(), you can get the card instance from codec->card, at least.

But currently SoC doesn't keep the PCM instances, so it cannot be implemented as it is... Liam, any plan or known issue regarding this?
