Some CEC (Consumer electronics control) notes:

The only mention I found is in the A20 user manual (But seems the info is applicable to A10).

There is a single register that is divided between CEC and HPD.

There is not much documentation other than HDMI pin 13 (CEC pin) being wired to P23.

No interrupt so far. The only way is to have a kernel thread looping and trying to read from the register (Are we sure which bit?)
