Seems like a v5 is shapping up. I'll summarise the discussion with
Daniel on IRC yesterday and with Ville on the thread:

- Let's adjust the timings (when it's needed) in the driver instead of
having user-space do it. This avoid leaking an implementation
detail, let user-space use the mode without having to tweak it and
Ville found that it'd be a bit impractical to match the 2D CEA VIC.
(Joakim Plate was wondering about this as well).

- Make drivers opt-in to expose stereo modes, just like today with
interlaced modes, giving an opportunity for people to make it work
people exposing the modes.

- For frame packing (where the framebuffer has to be twice as high +
vblank) we could also reject framebuffers with the wrong geometry.
