Well..  There probably are on a hardware level, but there's no interface
that exposes them to the kernel.. as far as I've seen. Resets are usually
managed via the blocks' registers. I can't say with certainty because I
don't have access to TRMs.

I can reword this commit message to make that clear.

Best regards,
Ivaylo
