If this is supposed to give people a clue about what these GPIOs are,
it completely fails to do this.  CT CP?  HPD is obviously the hotplug
detect signal, but why are there two - HDMI only has a single detect
pin on the connector.

While it makes sense to stick all three into one property, is it
possible that not all of these may be routed to a GPIO?  If so, how
do you specify that one (or more) of these does not exist?

Another issue here is that other HDMI encoders are available - should
every encoder define its own set of bindings, or should there be a
base set of bindings which all encoders should conform to - such as
always having a HDMI output port?
