[PATCHv2 0/9] omapdrm: hdmi4: add CEC support

[Hans Verkuil]

From: Hans Verkuil <hans.verkuil at cisco.com>

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
