2016-08-22[media] cec: add CEC_LOG_ADDRS_FL_ALLOW_UNREG_FALLBACK flagHans Verkuil
Currently if none of the requested logical addresses can be claimed, the framework will fall back to the Unregistered logical address. Add a flag to enable this explicitly. By default it will just go back to the unconfigured state. Usually Unregistered is not something you want since the functionality is very limited. Unless the application has support for this, it will fail to work correctly. So require that the application explicitly requests this.

2016-07-13[media] cec: split the timestamp into an rx and tx timestampHans Verkuil
When transmitting a message and waiting for a reply it would be good to know the time between when the message was transmitted and when the reply arrived. With only one timestamp field it was set to when the reply arrived and the original transmit time was overwritten. Just taking the timestamp in userspace right before CEC_TRANSMIT is called is not reliable, since the actual transmit can be delayed if the CEC bus is busy. Only the driver can fill this in accurately. So split up the ts field into an rx_ts and a tx_ts. Also move the status fields to after the 'reply' field: they were placed in a strange position and make much more sense when grouped with the other status-related fields. This patch also makes sure that the timestamp is taken as soon as possible. Signed-off-by: Hans Verkuil <hans.verkuil@cisco.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com>

2016-06-28[media] cec.h: add cec headerHans Verkuil
This header contains the CEC public API. Since the CEC framework will initially be part of staging this header is kept out of include/uapi for the time being until the CEC framework will be moved out of staging.
