I didn't catch any sort of announcement of it, but it seems as if we've
started using SPDX license identifiers in dts files. Thus you can simply
include the line
SPDX-License-Identifier: (GPL-2.0+ OR MIT)
after the copyright notice and omit the license notices themselves. Even
though the comment refers to "the X11 license", the license text matches that
associated with the MIT license identifier [1] rather than that of the X11
license [2]. The same goes for patch 5/6.

It's still not the prefixes I told you to use. I merged your patches
and fixed, but please use the right one next time (and be consistent
in your ARM vs arm usage).

Thanks for your work!

For my opinion on the matter, see this mail from RMK:
http://lists.infradead.org/pipermail/linux-arm-kernel/2017-February/490649.html

If people want to use it, I'm okay with that, but I really don't want
to actively enforce it during the reviews.

I'd like to at least have a common scheme across regular contributors,
and not the current mess that we have. So, yes, kind of. And it
doesn't make much sense these days where all our changes are either
drivers or dts.
