From: Hans Verkuil <hans.verkuil@xxxxxxxxx> This patch series adds the hotplug detect notifier code, based on Russell's code: https://patchwork.kernel.org/patch/9277043/ It adds support for it to the exynos_hdmi drm driver, adds support for it to the CEC framework and finally adds support to the s5p-cec driver, which now can be moved out of staging. Also included is similar code for the STI platform, contributed by Benjamin Gaignard. Tested the exynos code with my Odroid U3 exynos4 devboard. Comments are welcome. I'd like to get this in for the 4.12 kernel as this is a missing piece needed to integrate CEC drivers. Daniel, who should merge this? The HPD notifier code is in drivers/video (correctly, I think), but it is initially only used by CEC drivers which are in drivers/media (since CEC is part of the media subsystem). It would be easiest to merge it all through the media subsystem, but in that case I need Acks from you. The alternative is to merge the drivers/video and drivers/gpu patches via you and the others via media. It's a bit painful though due to the dependencies. Regards, Hans Changes since v3: - Added the STI patches - Split the exynos4 binding patches in one for documentation and one for the dts change itself, also use the correct subject and CC to the correct mailinglists (I hope :-) ) Changes since v2: - Split off the dts changes of the s5p-cec patch into a separate patch - Renamed HPD_NOTIFIERS to HPD_NOTIFIER to be consistent with the name of the source. Changes since v1: Renamed HDMI notifier to HPD (hotplug detect) notifier since this code is not HDMI specific, but is interesting for any video source that has to deal with hotplug detect and EDID/ELD (HDMI, DVI, VGA, DP, ....). Only the use with CEC adapters is HDMI specific, but the HPD notifier is more generic.
