For those who are interested in HDMI CEC support I made a little status
document that I intend to keep up to date:


My goal is to get CEC supported for any mainlined HDMI driver where the hardware
supports CEC.

If anyone is working on a CEC driver that I don't know already about, just drop
me an email so I can update the status.

I also started maintaining a list of DisplayPort to HDMI adapters that support
CEC. If you have one that works and is not on the list, then please let me know.
Seeing /dev/cecX is not enough, some adapters do not connect the CEC pin, so they
won't be able to detect any other CEC devices. See the test instructions in the
cec-status.txt file on how to make sure the adapter has a working CEC pin. I
plan to do some more testing this week, so hopefully the list will expand.
