Daniel Vetter 8f5718a6d9 drm/i915: drop unnecessary check from fdi_link_train code
They are all written for a specific north disaplay->pch combination.

Daniel Vetter 7fcb83cde0 drm/i915: check whether the pch is the soulmate of the cpu
We don't really support fancy north display/pch combinations, so
put a big yelling WARN_ON in there. It /should/ be impossible, but
alas, the rumours don't stop (mostly due to really early silicon
sometimes using older PCHs).

v2: Fixup the logic fumble noticed by Paulo Zanoni. I should actually
try to test run the patch next time around ...

Daniel Vetter 270b30420c drm/i915: move panel connectors to the front
This essentially reverts

Date:   Fri Jul 16 14:46:29 2010 -0400

    drm/i915: Initialize LVDS and eDP outputs before anything else

simply because it doesn't scale: It misses SDVO and DVO panels,
and now with DDI encoders on haswell this is becoming unmanageable.

Instead we simply sort the connector list after everything is
set up.

    drm/i915: Initialize LVDS and eDP outputs before anything else

    This makes them sort to the front in X, which makes them likely to be
    the primary outputs if you haven't specified a preference in your DE,
    which is likely to be what you want.

Paulo Zanoni 00c09d70df drm/i915: create the DDI encoder
Now intel_ddi_init is just like intel_hdmi_init and intel_dp_init: it
inits the encoder and then calls the proper init_connector functions.
Notice that for non-eDP ports we call both HDMI and DP connector init,
so we have 2 connectors attached to each DDI encoder.

After this change, intel_hdmi_init and intel_dp_init are only called
by Ivy Bridge and earlier, while hardware containing DDI outputs
should call intel_ddi_init.

Also added/removed quite a few "static" keywords due to the fact that
some function pointers were moved from intel_dp.c and intel_hdmi.c to
intel_ddi.c.

in the future the DDI code will have its own "encoder init" function,
but it will still call intel_hdmi_init_connector. The DDI encoder will
actually have two connectors attached to it: HDMI and DP.

The best way to look at this patch is to imagine that we're renaming

encoder-specific pieces and placing them into intel_hdmi_init.

Paulo Zanoni da63a9f2e4 drm/i915: create intel_digital_port and use it
The goal is to have one single encoder capable of controlling both DP
and HDMI outputs. This patch just adds the initial infrastructure, no
functional changes.

Previously, both intel_dp and intel_hdmi were intel_encoders. Now,
these 2 structs do not have intel_encoder as members anymore. The new
struct intel_digital_port has intel_encoder as a member, and it also
includes intel_dp and intel_hdmi as members. In other words: see the
changes inside intel_drv.h: it's the most important change, everything
else is only to make it compile and work.

For now, each intel_digital_port is still only able to control one of
HDMI or DP, but not both together.

In the future we should also try to merge the common fields from
intel_dp and intel_hdmi (e.g., port).

Paulo Zanoni 30add22d84 drm/i915: add intel_dp_to_dev and intel_hdmi_to_dev
When we add struct intel_digital_port, there will be no direct way of
going from intel_{dp,hdmi} to drm_device: we will need to call
container_of().

This patch adds functions to go from intel_{dp,hdmi} to drm_device.
The main goal here is to greatly reduce the size of the next patch,
where we will change the implementation of the functions we just
added here (among other things).

Paulo Zanoni fa90ecefdc drm/i915: simplify assignments inside intel_dp.c
- Replace container_of with enc_to_intel_dp.
 - Walk through less structures when making assignments.
 - Rename some variables to keep our naming standards.

As a bonus, this will reduce the usage of "struct intel_dp", making
the future patch that introduces intel_digital_port smaller and easier
to review.
