Compile-tested only.

NACK.

This was productized, there are some out in the wild, and the platform 
is still in (limited) use.

I'd like to see support hang around for a few more years yet.

The problem is that... its support is pretty strange. I can see
pinctrl, ethernet and quirks for the platform in GIC-ITS and PL011
drivers. Is this enough to get the platform into the useful state? I
can imagine that "QCOM2430" ACPI handle was used for USB hosts on that
platform, but I don't remember when we last tested DWC3 with the ACPI.

So, all this boils down to the question whether mainline (or something
close by, LTS for example) is actually used and tested on these
devices?

Its an ACPI system, so you won't see all of the fun DTisms of a MSM chip.

The platform was fully functional upstream, and had an Ubuntu 
certification.  I run Ubuntu on the two that I have in my office.  I 
haven't strictly checked out mainline in a while, but I could.  I still 
have access to the documentation.

There is a small, but active set of users including myself.  From what 
I've seen, they've been happy with things.

Thanks for the information! It looks like it has a small but stable
user base. I think we should keep it, maybe ensuring that we are able
to test the kernel.

Alright, please make sure it still boots etc. then!
