Looks alright, thanks for sending this. One nit below.

While I like those SPDX lines more, the Linux kernel copy still(?) uses
the more explicit license header. And we aim to stay as close as
possible to the kernel DTs, that includes comments as well.

So if you resend a v2 which just copies the kernel .dts, I will queue
it for the next merge window.

Cheers,
Andre

P.S. For the first version of a single patch "series", just use
"[PATCH]" in the subject. There is never a "v1", and also little reason
for a "1/1". If you have some comments that would typically go into a
cover letter, put them behind the "---" in the top of the email.
