Just to let you know:

I applied the set some days ago but this did not make to merge window.
Now, I put it on for-next branch so will appear on linux-next soon. I
also applied the fixes sent later.

I'll take also the latest work with interrupt mode for DMC (after minor
fix in bindings).

Best regards,
Krzysztof
