82 Property Sets and Device Tree Bindings
85 It often is useful to make _DSD return property sets that follow Device Tree
89 account in the first place and returning invalid property sets from _DSD must be
90 avoided.  For this reason, it may not be possible to make _DSD return a property
91 set following the given DT binding literally and completely.  Still, for the
92 sake of code re-use, it may make sense to provide as much of the configuration
94 ACPI-specific mechanism suitable for the use case at hand.
96 In any case, property sets following DT bindings literally should not be
