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)

Just to keep the paranoia equal also sprinkle locking asserts over the
pipestat interrupt enable/disable functions.
Again this results in false positives in the interrupt setup. Add
bogo-locking for these and a big comment explaining why it's there and
that it's indeed unnecessary.
v2: Fix up the spelling fail Paulo spotted in comments.

Use wait_for() instead of the open coded loop to avoid spreading the
same old timeout related bugs.
This changes the loop to use msleep(1) instead of udelay(10) when the
Punit had not yet completed the frequency change. In practice that
doesn't seem to hurt performance as the Punit appears to be ready pretty
much always.
Also give the status bit a name, instead of using the magic number 1.

We need this for comparing modes between configuration changes.
The tricky part is to allow us to reuse the new get_clock stuff to
recover the lvds clock on gen2/3 when neither the vbt has an lvds mode
nor the panel a (useful) EDID.

call get_clock after getting the encoder config, needed for pixel multiply
(Jesse)
v3: drop get_clock now that the pixel_multiply has been moved into
get_pipe_config
v4: re-add get_clock; we need to get the pixel multiplier in the
encoder, so need to calculate the clock value after the encoder's
get_config is called
v5: drop hsw clock_get, still needs to be written

Nothing outside of i915_gem_gtt.c and more specifically, the relevant
gen specific init function should need to know about number of PDEs, or
PTEs per PD. Exposing this will only lead to circumventing using the
upcoming VM abstraction.
To accomplish this, move the defines into the .c file, rename the PDE
define to be GEN6, and make the PTE count less of a magic number.
The remaining code in the global gtt setup is a bit messy, but an
upcoming patch will clean that one up.

Now that we have the proper pipe config to track this, we don't need
to write any registers any more.
Note that for platforms without DPLL_MD (pre-gen4) which store the
pixel mutliplier in the DPLL register I've decided to keep the
seemingly "redundant" write: The comment right below saying "do this
trice for luck" doesn't instill confidence ...
v2: Drop a few now unnecessary local variables and switch the enable
function to take a struct intel_crtc * to simply arguments.

v4: Amend commit message to alliviate Imre's comment about the
redudant DPLL write for the pixel mutliplier.

The ->pre_enable hook is only used for the cpu edp port on ilk-ivb, so
we can safely move it up across the fdi pll enabling.
Unfortunately we can't (yet) merge in the pre_pll enable hook despite
that only lvds uses it on ilk-ivb: Since the same lvds hook is also
need on i9xx platforms we need to fix up the pll enabling sequence
there, too.

Lots of bangin my head against the wall^UExperiments have shown that
we really need to enable the lvds port before we enable plls. Strangely
that seems to include the fdi rx pll on the pch.
Note that the pch pll assert can fire since the lvds port has it's own
special clock source settings in the DPLL register, which means it
will never have a shared dpll (since there's only one LVDS port).
Anyway, encode this new evidence with a few nice WARNs.
v2: Incorporate review comments from Imre.
- Explain why lvds can't have a shared dpll.
- Update the WARN output.

No code change, just duplication. Also kill a now seriously outdated
code comment - the remark about the dvo encoder is now handled with
the pipe A quirk.
v2: Update the BUG_ONs as suggested by Jani (both in vlv_ and i9xx_

Just yet another prep step to be able to do all this up-front, before
we've set up any of the shared dplls in the new state. This will
eventually be useful for atomic modesetting.

It's been splattered over 3 different places all doing random things.
Now we have (mostly) the same sequence as i8xx/i9xx, but all called
from the crtc_enable hook (through the pll->enable function):
- write new dividers
- enable vco and wait for stable clocks
- write again for the pixel mutliplier
I've left the seemingly random 200 usec delay in there, just in case.
Also move the encoder->pre_pll_enable hook into the crtc_enable
function, at the same spot we currently have a hack to enable the lvds
port. Since that hack is now redundant, kill it.
While doing this patch I've learned the hard way that we can only fire
up the LVDS port if both the pch dpll _and_ the fdi rc pll are not yet
enabled. Otherwise things go haywire, at least on cpt.
v2: It is paramount to write the FPx divisors before we enable the
the vco by writing to the DPLL registers, for otherwise the divisors
won't get updated. This is in line with the i8xx/i9xx dpll.
v3: To keep the nice abstraction add a ->mode_set callback to set the
divisors. Also streamline the enabling/disabling code a bit by
removing some cargo-cult duplication and clearing registers where
possible in the ->disable hook.
v4: Remove now unused local variable.

When running on my snb machine, recent kernels display successively:
[drm:intel_update_fbc], fbc set to per-chip default
[drm:intel_update_fbc], fbc disabled per module param
But no module param is set. This happens because the check for the
module parameter uses a variable that has been overridden inside the
"per-chip default" code.
Fix up the logic and add another reason for the FBC to the be disabled.

We currently print a DRM_DEBUG_KMS message on the happy path and don't
print anything on the "failed to allocate" path. On some desktop
environments (e.g., Unity) I see the "scheduling delayed FBC enable"
thousands and thousands of times on my dmesg.
So kill the useless message for the happy case, saving a lot of dmesg
space, and properly signal the "kzalloc fail" case.

In the old panel device model we had "outputs", which were the encoders
inside OMAP DSS block, and panel devices (omap_dss_device). The panel
devices had a reference to the source of the video data, i.e. reference
to an "output", in a field named "output".
That was somewhat confusing even in the old panel device model, but even
more so with the panel device model where we can have longer chains of
display entities.
This patch renames the "output" field to "src", which much better tells
what the field points to.

I2C of helpers used to live in of_i2c.c but experience (from SPI) shows
that it is much cleaner to have this in the core. This also removes a
circular dependency between the helpers and the core, and so we can
finally register child nodes in the core instead of doing this manually
in each driver. So, fix the drivers and documentation, too.
