That's not entirely true - the _DSD stuff was also actively being used
by the embedded x86 people since they needed firmware bindings for
things and wanted to import all the work that's been done for DT, or as
much as possible anyway given that there's bits of ACPI that actively
conflict with DT.  They were driving this much more actively and doing
much more extensive work than the ChromeOS people.  That all seems to
have been abandoned though.
