Let's kill this legacy iand almost unused rq_enabled version
in favor of the real one that is checked at
intel_irqs_enabled().

The commit 'ac1723c16b66 ("drm/i915: Track IRQ state

DRM level irq_enabled information that got removed.

But the driver one already existed under a different

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.

We do not have ALPM on DP Panel Replay. Due to this SRD_STATUS[SRD State]

On eDP Panel Replay DEEP_SLEEP is not reached.

a436c77ea2 Merge tag 'exynos-drm-next-for-v6.12' of git://git.kernel.org/pub/scm/linux/kernel/git/daeinki/drm-exynos into drm-next 
Three cleanups
- Drop stale exynos file pattern from MAINTAINERS file
  The old "exynos" directory is removed from MAINTAINERS as Samsung Exynos display bindings have been relocated. This resolves a warning from get_maintainers.pl about no files matching the outdated directory.

- Constify struct exynos_drm_ipp_funcs
  By making struct exynos_drm_ipp_funcs constant, the patch enhances security by moving the structure to a read-only section of memory. This change results in a slight reduction in the data section size.

- Remove unnecessary code
  The function exynos_atomic_commit is removed as it became redundant after a previous update. This cleans up the code and eliminates unused function declarations.

One fixup
- Fix wrong assignment in gsc_bind()
  A double assignment in gsc_bind() was flagged by the cocci tool and corrected to fix an incorrect assignment, addressing a potential issue introduced in a prior commit.
