From: Hans Verkuil <hans.verkuil@xxxxxxxxx> This patch series is an update to this RFC series from Russell: https://lists.freedesktop.org/archives/dri-devel/2016-August/115733.html I have not seen any updates to this, so I hope that that series is still the latest version. The main problem with that original series was that the notifier didn't store the state, so if a CEC driver registered with the notifier, then it wouldn't be informed of the current state. The hdmi-notifier code has been changed to a per-HDMI-device and refcounted block_notifier that stores the state and will report the current state upon registration. The other four patches have been adapted to the new notifier code, but no other changes were made. It has *only* been compile-tested. I might be able to verify it next week with an actual i.MX6 device, but it will take time to set that up. If someone has a ready-to-test setup, then I would very much appreciate it if this series can be tested. The patches are also available in my branch: https://git.linuxtv.org/hverkuil/media_tree.git/log/?h=cec-notifiers It is on top of my patch series that moves CEC out of staging. This is planned for 4.10.
