HDMI CEC wakeup source

Type of issue

Feature Request

HDMI CEC as a wakeup source is very useful for mediacenter type of device. You can turn on TV and with it, boards power ups or resumes from sleep. If OS is configured properly, this feature can provide very seamless integration and board and TV behave as one - if you turn on TV, board turns on too and vice-versa. Same goes for turning them off too.

Initially, simple functionality like waking up only would be enough. Later, CEC message processing can be implemented for notifying TV about power status and so on.

Initial implementation will be provided shortly.

Should we keep this open to track the TODO for more complete message processing?

Good point. However, this may take a while.
