This series updates DRM drivers to use new CEC notifier API. Changes since v6: Made CEC notifiers' registration and de-registration symmetric in tda998x and dw-hdmi drivers. Also, accidentally dropped one patch in v6 (change to drm_dp_cec), brought it back now. Changes since v5: Fixed a warning about a missing comment for a new member of drm_dp_aux_cec struct. Sending to a wider

...egrated GPU support and I only implemented this for the discrete GPU case. If someone has the integrated GPU and wants to get this working and is willing to do some testing, then please contact me. It shouldn't be difficult. You will likely have to buy a working DP-to-HDMI adapter. See https://hverkuil.home.xs4all.nl/cec-status.txt for a (sadly very short) list of working adapters. Note that I may be completely off-base regarding what atombios_dp.c does, it's the first time I ever looked at amdgpu code. Two notes on CEC-Tunneling-over-AUX: 1) You need to be very careful about which USB-C/D...

Reviewed-by: Lyude Paul <lyude at redhat.com> We really need to add support for using this into the MST helpers. A good way to test this would probably be to hook up an aux device to the DP AUX adapters we create for each MST topology On Fri, 2018-08-17 at 16:11 +0200, Hans Verkuil wrote: > From: Hans Verkuil <hans.verkuil at cisco.com> > > When parsing the reply of a

Pass the connector info to the CEC adapter. This makes it possible to associate the CEC adapter with the corresponding drm connector.

...ed on the new MegaChips 2900 fare much better: it appears that their reference design *does* hook up the CEC pin. Club3D has adapters using this device for USB-C, DP and mini-DP to HDMI, and they all work fine. If anyone finds other adapters that work besides those I list in https://hverkuil.home.xs4all.nl/cec-status.txt, please let me know and I'll add them to the list. Linux is the first OS that supports this feature, so I am not surprised that HW support for this has been poor. Hopefully this will change going forward.
