97e17a0906 drm/i915/xehp: Add register for compute engine's MMIO-based TLB invalidation 
Compute engines have a separate register that the driver should use to
perform MMIO-based TLB invalidation.

Note that the term "context" in this register's bspec description is
used to refer to the engine instance (in the same way "context" is used
on bspec 46167).

The remaining DG2 IDs for add-in cards will come in a future patch once
some additional required functionality has fully landed.

eddbb074ce drm/i915/dp: Add workaround for spurious AUX timeouts/hotplugs on LTTPR links 
To avoid AUX timeouts and subsequent spurious hotplug interrupts, make
sure that the first DPCD access during detection is a read from an LTTPR
register.

Some ADLP DP link configuration at least with multiple LTTPRs expects
the first DPCD access during the LTTPR/DPCD detection after hotplug to
be a read from the LTTPR range starting with
DP_LT_TUNABLE_PHY_REPEATER_FIELD_DATA_STRUCTURE_REV. The side effect of
this read is to put each LTTPR into the LTTPR transparent or LTTPR
non-transparent mode.

The lack of the above read may leave some of the LTTPRs in non-LTTPR
mode, while other LTTPRs in LTTPR transparent or LTTPR non-transparent
mode (for instance LTTPRs after system suspend/resume that kept their
mode from before suspend). Due to the different AUX timeouts the
different modes imply, the DPCD access from a non-LTTPR range will
timeout and lead to an LTTPR generated hotplug towards the source (which
the LTTPR firmware uses to account for buggy TypeC adapters with a long
wake-up delay).

SYSCROS: 72939

v2: Keep DPCD read-out working on non-LTTPR platforms.
v3: Summarize what and why the patch does at the beginning of the commit
    log. (Jani)

If bigjoiner is used hw.crtc is what tells us what crtc the plane

Not an actual problem on current hardware as the only FBC capable
pipe (A) can't be a bigjoiner slave and thus uapi.crtc==hw.crtc
always here. But when we get more FBC instances this will become

14eb76f73e drm/i915/fbc: s/false/0/ 
intel_fbc_check_plane() is supposed to an int, not a boolean.
So replace the bogus 'return false's with the correct 'return 0's.
These were accidental copy-paste mistakes when the code got moved
into intel_fbc_check_plane() from somewhere else tht did return
a boolean.

No functional issue here since false==0.

Not an actual problem on current hardware as the only FBC capable

always here. But when we get more FBC instances this will become

Move DRM's HMDI helpers into the display/ subdirectoy and add it
to DRM's display helpers. Update all affected drivers. No functional
changes.

The HDMI helpers were implemented in the EDID and connector code, but
are actually unrelated. With the move to the display-helper library, we
can remove the dependency on drm_edid.{c,h} in some driver's HDMI source
files.

Several of the HDMI helpers remain in EDID code because both share parts
of their implementation internally. With better refractoring of the EDID
code, those HDMI helpers could be moved into the display-helper library
as well.
