407569ff79 drm/i915: pass dev_priv to _MMIO_PIPE2, _MMIO_TRANS2, _MMIO_CURSOR2
Pass the dev_priv parameter to the low-level helpers, and move the
implicit dev_priv usage one level higher.

sed -i "s/\(_MMIO_PIPE2(\|_MMIO_TRANS2(\|_MMIO_CURSOR2(\)/\1dev_priv, /" \
	$(git ls-files drivers/gpu/drm/i915)

Name the parameter "display", as the generics allow it to be display
already.

2b981d57e4 drm/i915/display: Support PSR entry VSC packet to be transmitted one frame earlier
Display driver shall read DPCD 00071h[3:1] during configuration
to get PSR setup time. This register provides the setup time
requirement on the VSC SDP entry packet. If setup time cannot be
met with the current timings
(e.g., PSR setup time + other blanking requirements > blanking time),
driver should enable sending VSC SDP one frame earlier before sending
the capture frame.

BSpec: 69895 (PSR Entry Setup Frames 17:16)

v2: Write frames before su entry to correct register (Ville, Jouni)
    Move frames before su entry calculation to it's
    own function (Ville, Jouni)
    Rename PSR Entry Setup Frames register to indicate
    Lunarlake specificity (Jouni)
v3: Modify setup entry frames calculation function to
    return the actual frames (Ville)
    Match comment with actual implementation (Jouni)
v4: Drop "set" from function naming (Jouni, Ville)
    Use i915 instead of dev_priv (Jouni)

Reintroduce the special PSR AUX CH setup for hsw/bdw. Not all

460dc4ba14 drm/i915/psr: Fix BDW PSR AUX CH data register offsets
The multiplication got replaced by an addition in some cleanup.
This means we never write the correct data to some of the BDW
PSR data registers and thus we fail to actually wake up the
panel from PSR.

2590ef92cd drm/i915/psr: Define more PSR mask bits
Define more of the PSR mask bits, and describe in detail
what some of them do. Even if we don't set them all from
the driver they can be very useful during PSR debugging.
Having to trawl through bspec every time to find them is
not fun, and re-reverse engineering the behaviour every
time is time consuming (even if a bit more fun than spec
trawling).
