As there is 1:1 mapping between encoder and connector for the LVDS, the
goal is to simply reduce the amount of noise within the connector
functions, i.e. we split the encoder/connector for LVDS as best we can and
try to only operate on the LVDS connector from the connector funcs and the
LVDS encoder form the encoder funcs.

Pull drm merge (part 1) from Dave Airlie:
"So first of all my tree and uapi stuff has a conflict mess, its my
fault as the nouveau stuff didn't hit -next as were trying to rebase
regressions out of it before we merged.
Highlights:
- SH mobile modesetting driver and associated helpers
- some DRM core documentation
- i915 modesetting rework, haswell hdmi, haswell and vlv fixes, write
combined pte writing, ilk rc6 support,
- nouveau: major driver rework into a hw core driver, makes features
like SLI a lot saner to implement,
- psb: add eDP/DP support for Cedarview
- radeon: 2 layer page tables, async VM pte updates, better PLL
selection for > 2 screens, better ACPI interactions
The rest is general grab bag of fixes.
So why part 1? well I have the exynos pull req which came in a bit
late but was waiting for me to do something they shouldn't have and it
looks fairly safe, and David Howells has some more header cleanups
he'd like me to pull, that seem like a good idea, but I'd like to get

Remove redundant #inclusions of core DRM UAPI headers (drm.h, drm_mode.h and

Without this patch and the patch to make include the UAPI headers from the core

because the DRM code relies on specific -I flags to make #include "..." work

Manual backmerge of -rc7 to resolve a silent conflict leading to
compile failure in drivers/gpu/drm/i915/intel_hdmi.c.
This is due to the bugfix in -rc7:

drm/i915: HDMI - Clear Audio Enable bit for Hot Plug
Since this code moved around a lot in -next git put that snippet at
the wrong spot. I've tried to fix this by making the conflict explicit
by merging a version for next with:
commit 3cce574f0190dd149472059fb69267cf83d290f9
Author: Wang Xingchao <xingchao.wang@intel.com>
Date: Thu Sep 13 11:19:00 2012 +0800
drm/i915: HDMI - Clear Audio Enable bit for Hot Plug unconditionally
But that failed to solve the entire problem. To avoid pushing out
further -nightly branch to our QA where this is broken, do the
backmerge and manually add the stuff git adds to -next from the patch
in -fixes.
Note that this doesn't show up in git's merge diff (and hence is also
not handled by git rerere), which adds to the reasons why I'd like to
fix this with a verbose backmerge. The git merge diff only shows a
bunch of trivial conflicts of the "code changed in lines next to each
another" kind.

drm/i915: force mode set at lid open time
It was used to fix an issue on a i915GM based Thinkpad X41, which
somehow clobbered the modeset state at lid close time. Since then
massive amounts of things changed: Tons of fixes to the modeset
sequence, OpRegion support, better integration with the acpi code.
Especially OpRegion /should/ allow us to control the display hw
cooperatively with the firmware, without the firmware clobbering the
hw state behind our backs.
So it's dubious whether we still need this.
The second issue is that it's unclear who's responsibility it actually
is to restore the mode - Chris Wilson suggests to just emit a hotplug
event and let userspace figure things out.
The real reason I've stumbled over this is that the new modeset code
breaks drm_helper_resume_force_mode - it OOPSes derefing a NULL vfunc
pointer. The reason this wasn't caught in testing earlier is that in

i915: fix intel graphics suspend breakage due to resume/lid event
confusion
logic was added to _not_ restore the modeset state after a resume. And
since most machines are configured to auto-suspend on lid-close, this
neatly papered over the issue.
Summarizing, this shouldn't be required on any platform supporting
OpRegion. And none of the really old machines I have here seem to
require it either. Hence I'm inclined to just rip it out.
But in case that there are really firmwares out there that clobber the
hw state, replace it with a call to intel_modset_check_state. This
will ensure that we catch any issues as soon as they happen.

Together with the static helper functions drm_crtc_prepare_encoders

Also call our new set_mode instead of the crtc helper one now in all

Intel hw only has one MUX for encoders, so outputs are either not
cloneable or all in the same group of cloneable outputs. This neatly
simplifies the code and allows us to ditch some ugly if cascades in
the dp and hdmi init code (well, we need these if cascades for other
stuff still, but that can be taken care of in follow-up patches).
Note that this changes two things:
- dvo can now be cloned with sdvo, but dvo is gen2 whereas sdvo is
gen3+, so no problem. Note that the old code had a bug and didn't
allow cloning crt with dvo (but only the other way round).
- sdvo-lvds can now be cloned with sdvo-non-tv. Spec says this won't
work, but the only reason I've found is that you can't use the
panel-fitter (used for lvds upscaling) with anything else. But we
don't use the panel fitter for sdvo-lvds. Imo this part of Bspec is
a) rather confusing b) mostly as a guideline to implementors (i.e.
explicitly stating what is already implicit from the spec, without
always going into the details of why). So I think we can ignore this
- worst case we'll get a bug report from a user with with sdvo-lvds
and sdvo-tmds and have to add that special case back in.
Because sdvo lvds is a bit special explain in comments why sdvo LVDS
outputs can be cloned, but native LVDS and eDP can't be cloned - we
use the panel fitter for the later, but not for sdvo.
Note that this also uncoditionally initializes the panel_vdd work used
by eDP. Trying to be clever doesn't buy us anything (but strange bugs)
and this way we can kill the is_edp check.

LVDS is the first output where dpms on/off and prepare/commit don't
perfectly match. Now the idea behind this special case seems to be
that for simple resolution changes on the LVDS we don't need to stop
the pipe, because (at least on newer chips) we can adjust the panel
fitter on the fly.
There are a few problems with the current code though:
- We still stop and restart the pipe unconditionally, because the crtc
helper code isn't flexible enough.
- We show some ugly flickering, especially when changing crtcs (this
the crtc helper would actually take into account, but we don't
implement the encoder->get_crtc callback required to make this work
properly).
So it doesn't even work as advertised. I agree that it would be nice
to do resolution changes on LVDS (and also eDP) whithout blacking the
screen where the panel fitter allows to do that. But imo we should
implement this as a special case a few layers up in the mode set code,
akin to how we already detect simple framebuffer changes (and only
update the required registers with ->mode_set_base).
Until this is all in place, make our lives easier and just rip it out.
Also note that this seems to fix actual bugs with enabling the lvds
output, see:

On gen4+ we have a bitfield to specify from which pipe the backlight
controller should take it's clock. For PCH split platforms we've
already set these up, but only at initialization time. And without
taking into account the 3rd pipe added with ivb.
For gen4, we've completely ignored these. Although we do restrict lvds
to the 2nd pipe, so this is only a problem on machines where we boot
up with the lvds on the first pipe.
So restructure the code to enable the backlight on the right pipe at
modeset time.
v2: For odd reasons panel_enable_backlight gets called twice in a
modeset, so we can't WARN_ON in there if the backlight controller is
switched on already.
v3: backlight enable can also be called through dpms on, so the check
in there is legit. Update the comment to reflect that.

- Regroup definitions for BLC_PWM_CTL so that they're all together and
and ordered according to the bitfields.
- Add all missing definitions for BLC_PWM_CTL2.
- Use the BLM_ (for backlight modulation) prefix consistently.
- Note that combination mode (i.e. also taking the legacy backlight
control value from pci config space into account) is gen4 only.
- Move the new registers for PCH-split machines up, they're an almost
match for the gen4 defitions. Prefix the special PCH-only bits with
BLM_PCH_. Also add the pipe C select bit for ivb.
- Rip out the second pair of PCH polarity definitions - they're only
valid on early (pre-production) ilk silicon.
- Adapt the existing code to use the new definitions. This has the
nice benefit of killing a magic (1 << 30) left behind be Jesse
Barnes.
No functional changes in this patch.

Conflicts:
drivers/gpu/drm/i915/intel_display.c
Ok, this is a fun story of git totally messing things up. There
/shouldn't/ be any conflict in here, because the fixes in -rc6 do only
touch functions that have not been changed in -next.
The offending commits in drm-next are 14415745b2..1fa611065 which
simply move a few functions from intel_display.c to intel_pm.c. The
problem seems to be that git diff gets completely confused:
$ git diff 14415745b2..1fa611065
is a nice mess in intel_display.c, and the diff leaks into totally
unrelated functions, whereas
$git diff --minimal 14415745b2..1fa611065
is exactly what we want.
Unfortunately there seems to be no way to teach similar smarts to the
merge diff and conflict generation code, because with the minimal diff
there really shouldn't be any conflicts. For added hilarity, every
time something in that area changes the + and - lines in the diff move
around like crazy, again resulting in new conflicts. So I fear this
mess will stay with us for a little longer (and might result in
another backmerge down the road).

drm/i915: fixup interlaced vertical timings confusion, part 1
Unfortunately that commit failed to take into account that the lvds
code does some special adjustements to the crtc timings for upscaling
an centering.
Fix this by explicitly computing crtc timings in the lvds mode fixup
function and setting a special flag in mode->private_flags if the crtc
timings have been adjusted.
v2: Add a comment to explain the new mode driver private flag,
suggested by Eugeni Dodonov.
v3: Kill the confusing and now redundant set_crtcinfo call in
intel_fixed_panel_mode, noticed by Chris Wilson.

git://people.freedesktop.org/~danvet/drm-intel into drm-core-next
Daniel Vetter wrote
First pull request for 3.5-next, slightly large than usual because new
things kept coming in since the last pull for 3.4.
Highlights:
- first batch of hw enablement for vlv (Jesse et al) and hsw (Eugeni). pci
ids are not yet added, and there's still quite a few patches to merge
(mostly modesetting). To make QA easier I've decided to merge this stuff
in pieces.
- loads of cleanups and prep patches spurred by the above. Especially vlv
is a real frankenstein chip, but also hsw is stretching our driver's
code design. Expect more to come in this area for 3.5.
- more gmbus fixes, cleanups and improvements by Daniel Kurtz. Again,
there are more patches needed (and some already queued up), but I wanted
to split this a bit for better testing.
- pwrite/pread rework and retuning. This series has been in the works for
a few months already and a lot of i-g-t tests have been created for it.
Now it's finally ready to be merged. Note that one patch in this series
touches include/pagemap.h, that patch is acked-by akpm.
- reduce mappable pressure and relocation throughput improvements from
Chris.
- mmap offset exhaustion mitigation by Chris Wilson.
- a start at figuring out which codepaths in our messy dri1/ums+gem/kms
driver we actually need to support by bailing out of unsupported case.
The driver now refuses to load without kms on gen6+ and disallows a few
ioctls that userspace never used in certain cases. More of this will
definitely come.
- More decoupling of global gtt and ppgtt.
- Improved dual-link lvds detection by Takashi Iwai.
- Shut up the compiler + plus fix the fallout (Ben)
- Inverted panel brightness handling (mostly Acer manages to break things
in this way).
- Small fixlets and adjustements and some minor things to help debugging.
Regression-wise QA reported quite a few issues on ivb, but all of them
turned out to be hw stability issues which are already fixed in
drm-intel-fixes (QA runs the nightly regression tests on -next alone,
without -fixes automatically merged in). There's still one issue open on
snb, it looks like occlusion query writes are not quite as cache coherent
as we've expected. With some of the pwrite adjustements we can now
reliably hit this. Kernel workaround for it is in the works."

Instead of letting other modules directly access the ->gmbus array,
introduce intel_gmbus_get_adapter() for looking up an i2c_adapter
for a given gmbus port identifier. This will enable later refactoring
of the gmbus port list.
Note: Before requesting an adapter for a given gmbus port number, the
driver must first check its validity using i2c_intel_gmbus_is_port_valid().
If this check fails, a call to intel_gmbus_get_adapter() will WARN_ON and
return NULL. This is relevant for parts of the driver that read a port
from VBIOS, which might be improperly initialized and contain an invalid
port. In these cases, the driver must fall back to using a safer default
port.

With the introduction of the PCH, we gained an LVDS presence pin but we
continued to use the existing logic that asserted that LVDS was only
supported on certain mobile chipsets. However, there are desktop
IronLake systems with LVDS attached which we fail to detect. So for PCH,
trust the LVDS presence pin and quirk all the lying manufacturers.

Well almost anyway. IVB has 3 planes, pipes, transcoders, and FDI
interfaces, but only 2 pipe PLLs. So two of the pipes must use the same
pipe timings (e.g. 2 DP plus one other, or two HDMI with the same mode
and one other, etc.).
