This is what drives me crazy about Linux kernel development. I've been
doing this for 15 years, and I still get random emails that contradict
everything I've been told to date.

I was repeatedly told over the past year by multiple people that ARM64
server == ACPI, no ifs, ands, or buts.

Well, someone who actually has a DT-based ARM64 server system (which is
not me) should come up with such a definition.

I'm hoping that my driver can be accepted without DT support, and that
someone else who is interested in running my driver on an SBSA device
tree platform can add what's missing.
