Section 1.5.4, "DPLL A Control Register" from Bspec about bit 23
"FPA0/A1 P2 Clock Divide":
0 = Divide by 2
1 = Divide by 4. This bit must be set in DVO non-gang mode
So copy the current limits (which should be good for i8xx) and create
a new set for dvo encoders.

drm/i915: move i9xx dpll enabling into crtc enable function
that special DVO bit was lost. Some BSpec reading confirms that it's
only needed for DVO encoders. Section 1.5.4, "DPLL A Control Register"
for bit 30:
"2X Clock Enable. When driving In non-gang DVO modes such as a
connected flat panel or TV, a 2X" version of the clock is needed. When
not using the 2X output it should be disabled. This bit cannot be set
when driving the integrated LVDS port on devices such as Montara-GM."
Fix this regression up.

Embedding the node in the obj is more natural in the transition to VMAs
which will also have embedded nodes. This change also helps transition
away from put_block to remove node.
Though it's quite an uncommon occurrence, it's somewhat convenient to not
fail at bind time because we cannot allocate the node. Though in
practice there are other allocations (like the request structure) which
would probably make this point not terribly useful.
Quoting Daniel:
Note that the only difference between put_block and remove_node is
that the former fills up the preallocation cache. Which we don't need
anyway and hence is just wasted space.
v2: Clean up the stolen preallocation code.
Rebased on the reserve_node patches
renames ggtt_ stuff to gtt_ stuff
WARN_ON if the object is already bound (which doesn't mean it's in the
bound list, tricky)

With the getters in place from the previous patch this members serves no
purpose other than saving one spare pointer chase, which will be killed
in the next patch anyway.
Moving to VMAs, this members adds unnecessary confusion since an object
may exist at different offsets in different VMs.
v2: Properly preserve the stolen offset. This code is a bit hacky but it
all goes away when we embed the drm_mm_node and removes the need for the
incorrect patch I submitted previously: "Use gtt_space->start for stolen
reservation"

Soon we want to gut a lot of our existing assumptions how many address
spaces an object can live in, and in doing so, embed the drm_mm_node in
the object (and later the VMA).
It's possible in the future we'll want to add more getter/setter
methods, but for now this is enough to enable the VMAs.
v2: Reworked commit message (Ben)
Added comments to the main functions (Ben)

With the previous patch we no longer actually create a node, we simply
find the correct hole and occupy it. This very well could have been
squashed with the last patch, but since I already had David's review, I
figured it's easiest to keep it distinct.
Also update the users in i915. Conveniently this is the only user of the
interface.

For an upcoming patch where we introduce the i915 VMA, it's ideal to
have the drm_mm_node as part of the VMA struct (ie. it's pre-allocated).
Part of the conversion to VMAs is to kill off obj->gtt_space. Doing this
will break a bunch of code, but amongst them are 2 callers of
drm_mm_create_block(), both related to stolen memory.
It also allows us to embed the drm_mm_node into the object currently
which provides a nice transition over to the new code.
v2: Reordered to do before ripping out obj->gtt_offset.
Some minor cleanups made available because of reordering.
v3: s/continue/break on failed stolen node allocation (David)
Set obj->gtt_space on failed node allocation (David)
Only unref stolen (fix double free) on failed create_stolen (David)
Free node, and NULL it in failed create_stolen (David)
Add back accidentally removed newline (David)

r1xx asics have a slightly different surface register
setup compared to newer asics. There is no specific

Certain older rv770 asics have both a performance and
a 3D performance state rather than just multiple performance
levels in the state power state. The current code would
select the performance state rather than the 3D performance
state when the "performance" profile was selected. This change
switches to the "balanced" profile by default which ends up being
the internal performance profile. When the user selects the
"performance" profile, it selects the internal 3D performance
state so the user can select the higher performance modes.
For most asics this changes nothing. For certain rv770 asics
with static performance and 3D performance states, this allows
you to select between then using by selecting the "balanced"
and "performance" dpm profiles.
