I want to interact directly with the CEC protocol on my raspberry pi. How can I find out which device to use?

I understand the device name is /dev/vchiq, but you can't use it directly unless you get relevant VideoCore documentation. libcec uses the VideoCore API, which doesn't mention device names directly. Unless you want to use RPi-specific hardware features (and you know how to do it), you should just use libcec.
