Why didn't you include it in v9? I thought you had a working
implementation for this?

Since wakeup will be another case where glue and core need to interact,
it's good to have the wakeup implementation from the start to be able to
evaluate your multiport implementation properly.

Right now it looks like you only added wakeup interrupt lookup and
request, but then you never actually enable them which is not very nice.
