The MAINTAINERS file is not very helpful in this case.
You need to send dtc patches to the devicetree-compiler list
devicetree-compiler-u79uwXL29TY76Z2rM5mHXA@public.gmane.org
Subscription info is at
http://vger.kernel.org/vger-lists.html#devicetree-compiler
After changes are made by the dtc maintainer, we pull the new
version of dtc into the Linux tree.
