It isn't a series.  It's a prototype patch that I posted in one of the
previous threads earlier this month:

As I've said there, audio is not the only issue here, CEC also needs to
have access to much the same information that audio needs.

CEC needs to know two things: when the HDMI sink is disconnected, and
when the HDMI sink's EDID is available (specifically, CEC needs to know
the HDMI physical address for itself, which is passed as a number via
the EDID HDMI vendor block.)
