This patch series adds CEC support for the omap4. It is based on the 4.13-rc2 kernel with this patch series applied:
http://www.spinics.net/lists/dri-devel/msg143440.html
It is virtually identical to the first patch series posted in April:
http://www.spinics.net/lists/dri-devel/msg138950.html
The only two changes are in the Kconfig due to CEC Kconfig changes in 4.13 (it now selects CEC_CORE instead of depending on CEC_CORE) and a final patch was added adding a lost_hotplug op since for proper CEC support I have to know when the hotplug signal goes away.
Tested with my Pandaboard.
The lost_hotplug op is called only when the hotplug is lost, but I am happy to change it to an op that is called whenever the hotplug signal changes. Just let me know. I just implemented the minimal solution that I needed.
Regards,
Hans
