aed15309b9 drm/amd/display: Release fake sink 
If connector doesn't have a sink, fake sink is created, but
never released as it assumed that its destroyed with the
stream it is used for. But now sink is released before the
stream maintaing refcount consistency.

This way we also avoid assigning anything to connector keeping
all the operation local.

nospec quite reasonably asserts that it will never be used with an index
larger than unsigned long (that being the largest possibly index into an
C array). However, our ubi uses the convention of u64 for any large
integer, running afoul of the assertion on 32b. Reduce our index to an
unsigned long, checking for type overflow first.

2b5b63126e drm/i915: Simplify ilk-ivb underrun suppression 
Let's suppress the underruns around every modeset sequence instead
of trying to avoid it. Planes are disabled at this point anyway so
we don't really gain anything from keeping the underrun reporting
enabled. Also for PCH ports we already suppress all underruns here
anyway so trying avoid it for the CPU eDP doesn't seem all that
important.

Maybe this gets rid of some lingering spurious underruns?

952a08a21a drm/atmel-hlcdc: Stop using plane->fb 
We want to get rid of plane->fb on atomic drivers. Stop looking at it.

Daniel pointed out that the drm_framebuffer_put() in the plane cleanup
indicates that the driver doesn't shut things down cleanly. To do
that we should be able to just call drm_atomic_helper_shutdown(). Not
really sure the current cleanup sequence is actually sane, but whatever.

v2: Replace the drm_framebuffer_put() with
    drm_atomic_helper_shutdown() (Daniel)

ca3b3fa344 drm/i915: Consult VBT "LVDS config" bits to determine whether internal LVDS is present 
VBT seems to have some bits to tell us whether the internal LVDS port
has something hooked up. In theory one might expect the VBT to not have
a child device for the LVDS port if there's no panel hooked up, but
in practice many VBTs still add the child device. The "LVDS config" bits
seem more reliable though, so let's check those.

So far we've used the "LVDS config" bits to check for eDP support on
ILK+, and disable the internal LVDS when the value is 3. That value
is actually documented as "Both internal LVDS and SDVO LVDS", but in
practice it looks to mean "eDP" on all the ilk+ VBTs I've seen. So let's
keep that interpretation, but for pre-ILK we will consider the value
3 to also indicate the presence of the internal LVDS.

Currently we have 25 DMI matches for the "no internal LVDS" quirk. In an
effort to reduce that let's toss in a WARN when the DMI match and VBT
both tell us that the internal LVDS is not present. The hope is that
people will report a bug, and then we can just nuke the corresponding
entry from the DMI quirk list. Credits to Jani for this idea.

v2: Split the basic int_lvds_support thing to a separate patch (Jani)
v3: Rebase
v4: Limit this to VBT version >= 134

73b66f8731 drm/i915: Prepare GEM for suspend earlier 
In order to prepare the GPU for sleeping, we may want to submit commands
to it. This is a complicated process that may even require some swapping
in from shmemfs, if the GPU was in the wrong state. As such, we need to
do this preparation step synchronously before the rest of the system has
started to turn off (e.g. swapin fails if scsi is suspended).
Fortunately, we are provided with a such a hook, pm_ops.prepare().

v2: Compile cleanup
v3: Fewer asserts, fewer problems?

v4: Ville pointed out that in some circumstances (such as switching off
the overlay) the display code may issue a GPU request. This is
unexpected, and will result in us going to sleep with us believing the
GPU is still awake (though all user work has been saved). Add a comment
to remind our future selves of what trouble brews.
