Usually, vendor won't fix it, anyways, regardless of any kernel
workarounds.

Most Vendors are already completely overstrained w/ anything
software-related. A good reason why we should try to get rid firmware,
as much as we can.

It's really sad. A *decent* vendor would just provide a clean DT and
(actually matching!) schematics. But that's really hard to find, these
days :(
