[PATCHv3 0/5] video/exynos/cec: add HPD state notifier & use in s5p-cec

[Hans Verkuil]

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

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.

Tested with my Odroid U3 exynos4 devboard.

Comments are welcome. I'd like to get this in for the 4.11 kernel as
this is a missing piece needed to integrate CEC drivers.

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.

Regards,

	Hans
