I'd personally prefer to add this patch set at once to Eduardo's tree (of course with your ACKs). If so, we could see too many useless merge conflicts. Because your patches touch most of exynos DT stuff and that's why DT changes should be handled in Samsung tree if there is no problem ;) Let's wait for thermal guys. Let's target the latest version (v6) of this series. You can add my Acked-by: Eduardo Valentin edubez...@gmail.com OK, I'll take DT changes in my tree with your ack. in the DTS changes. And add them via your tree. I believe we will avoid merge conflicts this way. I will handle the patches touching drivers/.
