Hi, Team,
I read from below previous ticket that HDMI CEC functionality is not available at that time, and i want to know is there any update on this? Do this functionality work now? BTW I can't find any device tree description for this even in latest y6.1 kernel branch, so if yes, please also advice how to implentment it.
