Maybe there is a subtle change in how the HDMI connector has to be defined which is missing in our (private) DTB. Maybe the OMAP5-uEVM DTS gives a hint. A quick check shows last hdmi specific change for omap5-board-common or uevm was in 2017 but I may have missed something. There are 715a5a978733f0 and 671ab615bd507f which arrived in v5.7-rc1 as well and are related to hdmi clocks. So this may be (or not) and influencing factor. BR and thanks, Nikolaus
