Hi Maxime,

Thank you for your version 4 patch.
I tested all 78 patches based on the next-20200708.


Dual HDMI opearation does not work normally.
flip_done timed out occurs and doesn't work.
Could you check please it.

Thanks for testing and reporting this. I've been looking into it, and it
seems that it's not just the dual output that's broken, but HDMI1
entirely (so even a single display connected to HDMI1 doesn't work).

Is it happening for you as well?

Nevermind, I had the DSI panel connected and it was interfering
