Glad to see this. I've been suggesting folks use SPDX tags on dts
files as those are often dual licensed, so we have lots of license
boilerplate. But I've had some push back[1] but it's not something I
care to spend cycles on. It would be good to have some statement on
the use of tags. Anything new should use them (I can dust off my
checkpatch.pl check for this)? This is a good task for newbies? It's
each maintainer's decision? It's the copyright holder's (and their
lawyer's) decision?
