No offense was intended. My process has been to run my patches through get_maintainers.pl to get the list of addresses to copy on submissions and my 0016-dt-bindings-reserved-memory-introduce-designated-mov.patch solicited the '- ' address. My preference when reviewing is to receive an entire patch set to understand the context of an individual commit, but I can certainly understand that others may have different preferences. It was my understanding that the Devicetree specification list was part of the kernel (e.g. @vger.kernel.org) and would be willing to receive patches that might be of relevance to it. I am inexperienced with yaml and devicetree processes in general so I have tried to lean on the examples of other reserved-memory node bindings for help. There is much to learn and I am happy to modify my process to better accommodate your needs. Regards, Doug
