I think one of the issues they have here is that there's two cases that
need handling. There's the case of DT native platforms where the vendor
can write a sensible DT, but there's also the case of platforms that are
ACPI native with ACPI that is basically unusable by Linux since it
relies very heavily on being supplimented by a platform specific driver
blob. On those platforms there is little to no vendor support for
writing DT and you're stuck with some combination of reverse engineering
and reusing the ACPI data.
