Changes for example app and test-event to separate commit.
ie.
1) First patch to introduce API change and add capabalitly for existing drivers,
2) Add example app and test-event app change as next commit.

Found an EAL change, Please make a separate patch for EAL change
addressing master repo.
And make that patch depended on this series.
