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. Regards, Hans Changes since v5: - Add cec_notifier_set_phys_addr_from_edid(). This maps to an empty function if CONFIG_MEDIA_CEC_NOTIFIER is undefined. - Dropped the first cec-edid patch. It's no longer needed after the previous change. Changes since v4: - Dropped EDID/ELD/connect/disconnect support. Instead, just report the CEC physical address (and use INVALID when disconnecting). - Since this is now completely CEC specific, move it to drivers/media and rename to cec-notifier. - Drop block_notifier. Instead just set a callback for the notifier. - Use 'hdmi-phandle' in the bindings for both exynos and sti. So no vendor prefix and 'hdmi-phandle' instead of 'hdmi-handle'. - Make struct cec_notifier opaque. Add a helper function to get the physical address from a cec_notifier struct. - Provide dummy functions in cec-notifier.h so it can be used when CONFIG_MEDIA_CEC_NOTIFIER is undefined. - Don't select the CEC notifier in the HDMI drivers. It should only be enabled by actual CEC drivers. 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.
