Maciej, I'm cross-posting this to linux-media and the rc maintainer Sean Young. Note that various RC defines have been renamed in the upcoming 4.14. It might be better to base your code on top of https://git.linuxtv.org/media_tree.git/ which has those patches merged. Regards, Hans On

[PATCHv3 9/9] omapdrm: omapdss_hdmi_ops: add lost_hotplug op

The CEC framework needs to know when the hotplug detect signal disappears, since that means the CEC physical address has to be invalidated (i.e. set to f.f.f.f). Add a lost_hotplug op that is called when the HPD signal goes away. Signed-off-by: Hans Verkuil <hans.verk...@cisco.com> ---
