[Intel-gfx] [PATCH 0/8] lvds cleanup

[Daniel Vetter]

Hi all,

This is the first cleanup from my next stab at reworking the modeset code, with
the ultimate goal that we can compute the entire configuration (fdi config, pll
config, sharing of global resources) up-front, before touching the hw at all.
Together with some neat hw state readout this should make fastboot much more
solid, and obviously it's a requirement to properly implement the check mode of
atomic modeset.

Here I move some of the lvds stuff out of line, simple to better see through the
jungle. The newly-added pre_pll_enable callback might be unnecessary in the end,
since I think we should also move the pll enabling into the crtc_enable callback
and out of ->mode_set. Also, we need some notion of exclusive pch_pll (which the
lvds port needs to obey the modeset sequence) and stop disabling pch plls
unconditionally, since they might be in use by another active pipe. But that is
all stuff on top, once the entire clock handling rework settles.

For context, my current wip (iow: where I am stuck atm ...):

Comments, flames and test reports highly welcome.

Cheers, Daniel
