From: Hans Verkuil <hans.verkuil@xxxxxxxxx>
Besides various documentation and logging improvements, the main
addition to CEC is support for a special corner case:
When the physical address is invalid, it is still allowed by the CEC
specification to send messages from 0xf ('Unregistered') to 0 ('TV').
This is a workaround for devices that pull their HPD pin low when they
go into standby or switch to another input, even though CEC messages are
still working.
Regards,
Hans
