* this assumption becomes invalid in the future, the struct could be expanded
* to either (a) add more fields to allow power domain providers to store
* additional information, or (b) replace the id field with an opaque pointer,

* process during is .request op. This may require the addition of an extra op
* to clean up the allocation.
