fb48cb4355 drm/i915/display: use to_intel_uncore() to avoid i915_drv.h 
A number of places that include i915_drv.h only need it to get from
display to i915 to uncore. We have to_intel_uncore() for that, use it to
avoid the i915_drv.h include.

b8660fa662 drm/i915/dram: convert to struct intel_display 
Convert everything except uncore access to struct
intel_display. Converting the graphics version checks to display version
checks needs a tweak for display version 13, which have graphics version
12.

While at it, convert logging to drm_dbg_kms().

v2: Handle display version 13

188bdfb776 drm/i915: split out display register macros to a separate file 
This is a scripted split of the display related register macros from
i915_reg.h to display/intel_display_regs.h. As a starting point, move
all the macros that are only used in display code (or GVT). If there are
users in core i915 code or soc/, or no users anywhere, keep the macros
in i915_reg.h. This is done in groups of macros separated by blank
lines, moving the comments along with the groups.

Some manually picked macro groups are kept/moved regardless of the
heuristics above.

This is obviously a very crude approach. It's not perfect. But there are
4.2k lines in i915_reg.h, and its refactoring has ground to a halt. This
is the big hammer that splits the file to two, and enables further
cleanup.

76ec692721 drm/i915: Flag purely internal commits to not clear crtc_state->inherited 
If we have to force the hardware to go through a full modeset
due to eg. cdclk reprogramming, we need to preserve
crtc_state->inherited for all crtcs that have not otherwise
gone through the whole compute_config() stuff after connectors
have been detected.

Otherwise eg. cdclk induced modeset glk_force_audio_cdclk()
will clear the inherited flag, and thus the first real commit
coming from userspace later on will not be forced through
the full .compute_config() path and so eg. audio state may
not get properly recomputed.

But instead of adding all kinds of ad-hoc crtc_state->inherited
preservation hacks all over, let's change things so that we
only clear it for the crtcs directly included in userspace/client
initiated commits.

Should be far less fragile since now we just need to remember
to flag the internal commits, and not worry about where new
crtcs might get pulled in.

back to 2010 and commit 7f8a85698f ("drm/i915: Add the support of
memory self-refresh on Ironlake"), with no explanations, and it's been
copied and modified from that ever since. Finally drop it.

If the value are actually zero, the ilk_compute_*_wm() functions should
handle it gracefully.
