dfecc2952e drm/xe/display: remove compat raw reg read/write support 
The i915 display code no longer uses these interfaces. Remove them.

8d9908e8fe drm/i915/display: remove small micro-optimizations in irq handling 
The raw register reads/writes are there as micro-optimizations to avoid
multiple pointer indirections on uncore->regs. Presumably this is useful
when there are plenty of register reads/writes in the same
function. However, the display irq handling only has a few raw
reads/writes. Remove them for simplification.

92699ba956 drm/i915: Extract intel_post_plane_update_after_readout() 
Clean up the main commit_tail() codepath a bit by pulling
the post plane update steps that need to performed after
readout into their own little function
(intel_post_plane_update_after_readout()).

Declutters intel_atomic_commit_tail() a bit, and should
hopefully aid in keeping intel_pre_plane_update() vs.

ae5d0397b7 drm/i915/display: Enhance iterators for modeset en/disable 
Joiners have specific enabling and disabling order dependent on primary
and secondary pipes. This becomes more complex with ultrajoiner where we
have ultrajoiner primary/secondary pipes in addition to bigjoiner
primary/secondary pipes. To unify the approach that works for present
and future joiner cases, use primary and secondary pipe masks to
iterate over pipes.

If joiner is used, derive bigoiner primary and secondary pipe masks
and use following sequences:
Disabling : disable primary pipes followed by secondary pipes,
Enabling: enable secondary pipes followed by primary pipes.

This works well with ultrajoiner too, as ultrajoiner has 2 bigjoiner
primary/secondary pairs (AC, BD).

For non joiner case, enable/disable based on usual pipe order A-D, D-A
respectively.

v2:
-Simplify the iterator macro. (Ville)
-Use struct intel_display. (Ville)
-Add prefix _intel to the helper name. (Ville)

0644d2be99 drm/i915: Add some essential functionality for joiners 
In most of the cases we now try to avoid mentioning things like
"bigjoiner" or "ultrajoiner" trying to unify the API and refer
mostly to all this functionality as "joiner".
In majority cases that should be way to go.
However in some cases we still need to distinguish between
bigjoiner primaries and secondaries(such as DSC register programming).

Create correspondent helper functions and start using them,
in order be prepared for adding ultrajoiner functionality.

v2: Fixed checkpatch warnings (Ankit)
v3: Introduce ultrajoiner helpers in next patch.
v4: Streamline the helpers and add few more. (Ville)
v5: Add comment to clarify that helpers apply to both bigjoiner and
uncompressed joiner configurations. (Ville)

Add dedicated intel_display_caps for display, with device info and
params. Intentionally prefix the file intel_ instead of i915_. Going

Remove display param dumping from i915 specific i915_capabilities

Note that we don't add node_to_intel_display() functionality in

f7c2ed9d4c drm/i915/dp: Fix AUX IO power enabling for eDP PSR 
Panel Self Refresh on eDP requires the AUX IO power to be enabled
whenever the output (main link) is enabled. This is required by the
AUX_PHY_WAKE/ML_PHY_LOCK signaling initiated by the HW automatically to
re-enable the main link after it got disabled in power saving states
(see eDP v1.4b, sections 5.1, 6.1.3.3.1.1).

The Panel Replay mode on non-eDP outputs on the other hand is only
supported by keeping the main link active, thus not requiring the above
AUX_PHY_WAKE/ML_PHY_LOCK signaling (eDP v1.4b, section 6.1.3.3.1.2).
Thus enabling the AUX IO power for this case is not required either.

Based on the above enable the AUX IO power only for eDP/PSR outputs.

Bspec: 49274, 53370

v2:
- Add a TODO comment to adjust the requirement for AUX IO based on
  whether the ALPM/main-link off mode gets enabled. (Rodrigo)

26c85e7f40 drm/i915: Do not explicilty enable FEC in DP_TP_CTL for UHBR rates 
In case of UHBR rates, we do not need to explicitly enable FEC by writing
to DP_TP_CTL register.
For MST use-cases, intel_dp_mst_find_vcpi_slots_for_bpp() takes care of
setting fec_enable to false. However, it gets overwritten in
intel_dp_dsc_compute_config(). This change keeps fec_enable false across
MST and SST use-cases for UHBR rates.

While at it, add a comment explaining why we don't enable FEC in eDP v1.5.
