For the coresight part: Reviewed-by: Mathieu Poirier <mathieu.poirier@xxxxxxxxxx>

You probably want to split this patch in half so that Rafael can pick up the
the first part of it in his tree.

I am done reviewing the core part of this set and will do 33-36 next week. For
the next revision I would leave them out and send a separate set in order to
avoid delaying the ACPI part.

Thanks,
Mathieu
