Xtensa? Which SoC has an Xtensa core?

Unfortunately, there's been a submission of the same driver earlier this week:
https://lore.kernel.org/lkml/cover.1605693132.git.wilken.gottwalt@posteo.net/

It would be great if you could point out whatever issue there is with
that patch series (it looks like the retry delay could be useful for
example).

Thanks!
