I was able to debug this a bit more, and it seems the encoder_helper_funcs
don't like the prepare/commit callbacks and like enable better.
So when I do something similar to Marks patch a8eef71d38da ("drm/rockchip:
dw_hdmi: use encoder enable function"), like in the attached patch (to be
folded into the original addition of those functions), I get display output
again.
