I'm doing some testing with this series on my panda. One issue I see is that when I unload the display modules, I get: [ 75.180206] platform 58006000.encoder: enabled after unload, idling [ 75.187896] platform 58001000.dispc: enabled after unload, idling [ 75.198242] platform 58000000.dss: enabled after unload, idling So I think something is left enabled, most likely in the HDMI driver. I haven't debugged this yet. The first time I loaded the modules I also got "operation stopped when reading edid", but I haven't seen that since. Possibly not related to this series. Are there some simple ways to test the CEC? My buildroot fs has cec-compliance, cec-ctl and cec-follower commands. Are you familiar with those? Can they be used? Tomi
