Yeah, bad example, we should fix that text up.  Care to send a patch? :)

Yes, please don't use it if at all possible.

I see it is only used in a very small number of dts files.  Why not just
use BSD-2-Clause instead?  What do you find in ISC that is not available

The license is functionally equalivant to BSD-2, so why would you want
to add more complexity here and have two licenses that are the same be
"recommended"?
