I am not sure if this is the best way to fix the issue, but after 9736e988d328 Beaglebone-Black HDMI is totally broken and this fixes the issue. I am currently working on atomic modesetting for tilcdc, but there is no way it makes it to 4.5 release.
Yes, I'm not a big fan of the change either. I would've thought that you only need to update the .dpms pointer, all other hooks added are specific to atomic operations (right?). Would it not be simpler to have a tda998x_connector_dpms() function that calls the appropriate .dpms function based on the feature check?
Oh yes, that sound like a better idea, but si and appears to work too. I'll send another patch soon. Thanks.
