1938e59ab7 drm/i915/chv: Added CHV specific register read and write and Streamline CHV forcewake stuff
Support to individually control Media/Render well based on the register access.
Add CHV specific write function to habdle difference between registers
that are sadowed vs those that need forcewake even for writes.

Streamline the CHV forcewake functions just like was done for VLV.

This will also fix a bug in accessing the common well registers,
where we'd end up trying to wake up the wells too many times
since we'd call force_wake_get/put twice per register access, with
FORCEFAKE_ALL both times.

v2: Drop write FIFO for CHV and add comman well forcewake (Ville)
    Re-factor CHV/VLV Forcewake offsets (Ben)

v3: Fix for decrementing fw count in chv read/write. (Deepak)

v4: Squash the patches (Mika)

6118efe596 drm/i915: move psr_setup_done to psr struct
"Because our driver assumes only one panel is PSR capable, and we
already have other PSR information on dev_priv instead of intel_dp. If
we ever support multiple PSR panels, we'll have to move struct
i915_psr to intel_dp anyway." (by Paulo)

v2: Avoid more than one setup. Removing initialization
    and trusting allocation. (By Paulo Zanoni).
v3: rebase.
v4: Adding comment.

4874322e78 drm/nouveau/dp: fix support for dpms
SOR_PWR has no effect to power-off DP links, unlike other SOR protocols.

Instead, on the source side, we cut power to the lanes after having put
the sink into D3.  Link training takes care of everything required to
bring it back again.

55f083c33f drm/nouveau/disp/dp: maintain link in response to hpd signal
This previously worked for the most part due to userspace doing a
modeset in response to HPD interrupts.  This will allow us to
properly handle cases where sync is lost for other reasons, or if
userspace isn't caring.

d2ae2eb469 drm/nouveau/i2c: balance port acquire/release
This was a half-finished hack before, just enough to handle the shared
aux/i2c pad thing on G94 and up.

We got lucky with locking etc up until now, as this was (generally) all
protected by the DRM mode_config lock.  It's about to become a lot more
likely to hit the races.

af4870e406 drm/nouveau/kms/nv04-nv40: fix pageflip events via special case.
Cards with nv04 display engine can't reliably use vblank
counts and timestamps computed via drm_handle_vblank(), as
the function gets invoked after sending the pageflip events.

Fix this by defaulting to the old crtcid = -1 fallback path
on <= NV-50 cards, and only using the precise path on NV-50
and later.
