by Andrei Laperie:

note, that while this issue is marked 'in progress' we might need to postpone it past 1.7 if we won't get any 4.2 supportive hardware to verify the functionality

by Johan Hedberg:

It doesn't look likely that this will make it to 1.7 since we don't have proper controller support yet. Changing the target to 1.8.
