I've forgotten to add a commit addition discussed with Ville:

"Note that since the lvds code unconditionally sets the crtc timings, we
can also unconditionally set the respective flag and not just when we set
special timings like the old code did."

I'll smash another paragraph for you on top (which also address an
issue raised by Paulo):

"This requires that we pass the pipe config around to encoders, so
that they can set special attributes and set constraints. To do so
introduce a new ->compute_config encoder callback, which is called in
stead of the drm crtc helper's ->mode_fixup.

"To avoid massive churn all over the codebase we don't want to convert
all existing ->mode_fixup functions. Instead I've opted to convert
them on an as-needed basis (mostly to cut down on rebase conflicts and
to have more freedom to experiment around while developing the
patches)."

Cheers, Daniel
