I might suggest (a) sending the email "To" the DT maintainer, rather
than just CC'ing him, (b) perhaps start a new thread just to present
the proposed DT binding, and get feedback on that. A thread with a new
subject like "[RFC] DT binding for thermal zones" might get more
attention than a patch submission; the subject line of this patch
doesn't stand much (since it implies to me it's more about build
issues than DT bindings even though it does mention DT).
