Does upstreaming also cover patches for official Foundation HATS like the sense HAT too?

lategoodbye commented 6 years ago

This issue is more intended for minor general platform patches which hasn't been upstreamed yet. Overlays and especially the sense hat with its mfd driver is a different thing. But everyone is invited to send patches.
