d361ae269f drm/i915: make intel_aux_display_runtime_get get runtime PM, not PC8
Because we merged the PC8 and runtime PM features, so calling
intel_runtime_pm_get now has the same meaning, and we plan to just
remove hsw_disable_package_c8 for this exact reason.

My first patch tried to completely kill
intel_aux_display_runtime_get/put, because I was assuming that whoever
needed more than just runtime PM would have to get the appropriate
power domain instead of that, but it seems some people still want the
intel_aux_display_runtime_get abstraction, so keep it until someone
else tries to replace it with the more-standard power domain calls.

ba0239e03f drm/i915: remove dev_priv->pc8.requirements_met
The requirements_met variable was used to track two things: enabled
CRTCs and the power well. After the latest chagnes, we get a runtime
PM reference whenever we get any of the power domains, and we get
power domains when we enable CRTCs or the power well, so we should
already be covered, not needing this specific tracking.

9e6ea71a59 drm/i915: get/put runtime PM when we get/put a power domain
Any power domain will require the HW to be in PCI D0 state, so just do
the simple thing.

Dear maintainer: since intel_display_power_put() and
intel_display_power_get() are almost identical, git-am has failed
apply the patch on my local machine once: it added both chunks to
put(), instead of one chunk to get() and another to put(). When you
apply this patch to your tree, please check if it is correct.

a8a8bd547e drm/i915: make PC8 be part of runtime PM suspend/resume
Currently, when our driver becomes idle for i915.pc8_timeout (default:
5s) we enable PC8, so we save some power, but not everything we can.
Then, while PC8 is enabled, if we stay idle for more
autosuspend_delay_ms (default: 10s) we'll enter runtime PM and put the
graphics device in D3 state, saving even more power. The two features
are separate things with increasing levels of power savings, but if we
disable PC8 we'll never get into D3.

While from the modularity point of view it would be nice to keep these
features as separate, we have reasons to merge them:
 - We are not aware of anybody wanting a "PC8 without D3" environment.
 - If we keep both features as separate, we'll have to to test both
   PC8 and PC8+D3 code paths. We're already having a major pain to
   make QA do automated testing of just one thing, testing both paths
   will cost even more.
 - Only Haswell+ supports PC8, so if we want to add runtime PM support
   to, for example, IVB, we'll have to copy some code from the PC8
   feature to runtime PM, so merging both features as a single thing
   will make it easier for enabling runtime PM on other platforms.

This patch only does the very basic steps required to have PC8 and
runtime PM merged on a single feature: the next patches will take care
of cleaning up everything.

v2: - Rebase.
v3: - Rebase.
    - Fully remove the deprecated i915 params since Daniel doesn't
      consider them as part of the ABI.
v4: - Rebase.
    - Fix typo in the commit message.
v5: - Rebase, again.
    - Add a huge comment explaining the different forcewake usage
      (Chris, Daniel).
    - Use open-coded forcewake functions (Daniel).

262ca2b08f drm/i915: Rename similar plane functions to avoid confusion
The name 'update_plane' was used both for the primary plane functions in
intel_display.c and the sprite/overlay functions in intel_sprite.c.
Rename the primary plane functions to 'update_primary_plane' to avoid
confusion.

On a similar note, intel_display.c already had a function called
intel_disable_primary_plane() that programs the hardware to disable a
pipe's primary plane.  When we hook up primary planes through the DRM
plane interface, one of the natural handler names will be
intel_primary_plane_disable(), which is very similar.  To avoid
confusion, rename the existing intel_disable_primary_plane() to
intel_disable_primary_hw_plane() to make the two names a little more
distinct.

9297ebf29a drm/i915: Do not dereference pointers from ring buffer in evict event
The TP_printk() should never dereference any pointers, because the ring
buffer can be read at some unknown time in the future. If a device no
longer exists, it can cause a kernel oops. This also makes this
event useless when saving the ring buffer in userspaces tools such as
perf and trace-cmd.

The i915_gem_evict_vm dereferences the vm pointer which may also not
exist when the ring buffer is read sometime in the future.

The reordered setup sequence ended up calling del_timer_sync before

Compared to Ben's patch (which moved around the setup_timer call to
sanitize_early) this moves the sanitize_early call around in the
driver load call. This way we avoid calling setup_timer again in the
resume code (where we also call sanitize_early).

Let the drivers specify the name of the I2C-over-AUX adapter to maintain

The i915 driver currently uses DPDDC-A to DPDDC-D as names for the DP
i2c adapters. These names show up in the i2c sysfs name attribute. We'd
like to be able to maintain that when switching over to the new helpers.

Due to i2c device and connector cleanup ordering issues we also recently
made the drm device (instead of connector) the parent of the i2c
adapters:

978c605016 Merge branch 'drm-docs' of ssh://people.freedesktop.org/~danvet/drm into drm-next
Here's my drm documentation update and driver api polish pull request.
Alex reviewed the entire pile, I've applied a little bit of spelling
polish in a few places since then and otherwise the Usual Suspects (David,
Rob, ...) don't seem up to have another look at it (I've poked them on
irc). So I think it's as good as it gets ;-)

Note that I've dropped the final imx breaker patch since that's blocked on
imx getting sane. Once that's landed I'll ping you to pick up that
straggler.
