8b293eb53a drm/i915: Track the last-active inside the i915_vma 
Using a VMA on more than one timeline concurrently is the exception
rather than the rule (using it concurrently on multiple engines). As we
expect to only use one active tracker, store the most recently used
tracker inside the i915_vma itself and only fallback to the rbtree if
we need a second or more concurrent active trackers.

v2: Comments on how we overwrite any existing last_active cache.
v3: __list_del_entry() before list_replace_init() is confusing and, much
more important, entirely redundant.
v4: Note that both last_active and the rbtree may be simultaneously
tracking this timeline, albeit with different requests, and so the vma
may be retired twice for the same timeline.
v5: No, that list_del is required!

5c3f8c221c drm/i915: Track vma activity per fence.context, not per engine 
In the next patch, we will want to be able to use more flexible request
timelines that can hop between engines. From the vma pov, we can then
not rely on the binding of this request to an engine and so can not
ensure that different requests are ordered through a per-engine
timeline, and so we must track activity of all timelines. (We track
activity on the vma itself to prevent unbinding from HW before the HW
has finished accessing it.)

v2: Switch to a rbtree for 32b safety (since using u64 as a radixtree
index is fraught with aliasing of unsigned longs).
v3: s/lookup_active/active_instance/ because we can never agree on names

a523697857 drm/i915: Start returning an error from i915_vma_move_to_active() 
Handling such a late error in request construction is tricky, but to
accommodate future patches which may allocate here, we potentially could
err. To handle the error after already adjusting global state to track
the new request, we must finish and submit the request. But we don't
want to use the request as not everything is being tracked by it, so we
opt to cancel the commands inside the request.

b79ebe74e1 drm/i915/ddi: Simplify get_encoder_power_domains() 
We can simplify the encoder's get_power_domains() hook by calling it
only if the encoder is active. That way the hook can return its power
domains unconditionally without checking the active state by calling
encoder::get_hw_state(). This get_hw_state() query is in fact
redundant since it's already done by intel_modeset_readout_hw_state()
setting the encoder's crtc or leaving it NULL accordingly. Let's use
this fact to decide if the encoder is active.

While at it clarify the comment in intel_ddi_get_power_domains() about
primary vs. fake MST encoders and make sure we never do an incorrect
encoder->dig_port cast for fake MST encoders.

e518634b43 drm/i915/dsi: use vlv and bxt prefixes for the global DSI functions 
Avoid confusion with the functions to be added for the new ICL or gen 11
DSI implementation by renaming the current DSI functions. While at it,
permutate the words in the function names to make them all start with
"vlv_dsi" or "vlv_dsi_pll" etc.

Reduce the platform abstractions in the PLL file while at it, moving the
checks to vlv_dsi.c instead, where we typically already have the
necessary if ladders.

Leave the static functions as-is for now; they could be renamed later if
needed.

No functional changes.

v2: use "gen7" prefix.

v3: use "vlv" and "bxt" prefixes, reduce the abstractions.

ca3589c118 drm/i915/dsi: rename the current DSI files based on first platform 
Starting from ICL or gen 11 we have a new DSI block which requires
completely different programming from the current implementation. Having
them in the same file would be confusing. Rename the current DSI and DSI
PLL implementation files as vlv_dsi.c and vlv_dsi_pll.c.

No functional changes.

v2: use "gen7" prefix.

v3: use "vlv" prefix.

c4e4f4545b drm/i915/selftests: Fail hangcheck testing if the GPU is wedged 
If the GPU is irrecoverably wedged on startup, it means that it failed
on initialisation and we have already tried to reset it but failed. We
can ignore all further testing, as it is already dead. Failing early,
prevents us from slowly failing in our endeavours later and timing out.

c78d1f9d95 Merge tag 'exynos-drm-fixes-for-v4.18-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/daeinki/drm-exynos into drm-fixes 
Fixups
- Fix several problems to IPPv2 merged to mainline recentely.
  . An align problem of width size that IPP driver incorrectly
    calculated the real buffer size.
  . Horizontal and vertical flip problem.
  . Per-plane global alpha for XRGB modes.
  . Incorrect variant of the YUV modes.
- Fix plane overlapping problem.
  . The stange order of overlapping planes on XRGB modes
    by setting global alpha value to maximum value.

Cleanup
- Rename a enum type, drm_ipp_size_id, to one specific to Exynos,
  drm_exynos_ipp_limit_type.
- Replace {un/reference} with {put,get} functions.
  . it replaces several reference/unreference functions with Linux
    kernel nameing standard.
