There's multiple different camps trying to use ACPI for very different
things.  There's the server people on both x86 and ARM who want to use
standard ACPI and nothing but with the power management all hidden in
the AML but there's also the embedded x86 people who have the same needs
as DT platforms but find themselves unable to use DT so have to map all
the DT support into ACPI.  This has been accepted in areas that clearly
don't overlap with areas where there are existing ACPI bindings for
things, power management is one area where there are clear bindings
though.
