Yes, but as a whole there's no alignment in this file. Even the rest
of the entries for the hunk below aren't aligned.
Perhaps this form would be better:
# Colibri iMX6ULL Wi-Fi / BT Module on Colibri Eval Board
- toradex,colibri-imx6ull-wifi-eval
But I really don't want to go fix this in the whole file...

News to me. I thought 'enum' indicates that. My preference here is a
blank line just between DT properties.

Yes, and it was 102. For yamllint I actually put it at 110 just to get
to a reasonable number that I wanted to fix and warning free. I think
I fixed all non comment cases to be less than 100 and comments to be
up to 110.

Indeed.

That was not the purpose here. The '- |' line was indented 1 too many.
IIRC, the parser is not happy if you only change that line, so at
least the 1st line of the example had to be updated anyways.

I've said this before, but until example indentation is automatically
checked I'm not going to care.

Nope, as that's not a WS or linter thing. Alphabetical order is about
the only thing I look at reviewing additions to this, but I'm sure
some errors have slipped in.
Thanks for taking a look.
