The output is already enabled in .dpms(), doing it in .mode_set() too can cause noticeable flicker.
I think this should be coupled with "drm/tegra: DPMS off/on in encoder prepare/commit" that I sent earlier this week. Without it, the driver can get into a state where connector status is on, but the output is disabled.
I'm not sure I exactly understand which problem that patch fixes, but I'll give it some testing to see if it doesn't break anything.
