Lots of comments with missing spaces in them, there's quite a few examples of that in here.

All the ASoC and regmap APIs are _GPL(), you really shouldn't export new interfaces based on them without it - the point with the _GPL() is that non-GPL code shouldn't be able to use the APIs.

Do you need to export the individual ops rather than just the ops structure?

That's way too noisy, dev_dbg() at most.

Why is the lock global and not part of the AFE struct?

Is this really worth it over just calling _period_elapsed() directly?
