[PULL] drm-intel-next

[Jani Nikula <jani.nikula@intel.com>]

Hi Dave & Sima -

Here's the second i915 feature pull request for v6.17, mostly just
display changes.

Rodrigo will handle the subsequent (likely just fixes) pull requests for
v6.17, if any.


BR,
Jani.

  (Ville)
- Add support for Wildcat Lake (WCL) display, version 30.02 (Matt Roper, Matt
  Atwood, Dnyaneshwar)
- Extend drm_panel and follower support to DDI eDP (Arun)

Refactoring and cleanups:
- Make all global state objects opaque (Jani)
- Move display works to display specific unordered workqueue (Luca)
- Add and use struct drm_device based pcode interface (Jani, Lucas)
- Use clamp() instead of max()+min() combo (Ankit)
- Simplify wait for power well disable (Jani)
- Various stylistics cleanups and renames (Jani)

Fixes:
- Deal with loss of pipe DMC state (Ville)
- Fix PTL HDCP2 stream status check (Suraj)
- Add workaround for ADL-P DKL PHY DP and HDMI (Nemesa)
- Fix skl_print_wm_changes() stack usage with KMSAN (Arnd Bergmann)
- Fix PCON capability reads on non-branch devices (Chaitanya)
- Fix which platforms have ultra joiner (Ankit)

DRM core changes:
- Add ttm_bo_kmap_try_from_panic() for xe drm_panic support (Jocelyn Falempe)
- Add private pointer to struct drm_scanout buffer for xe/i915 drm_panic support
  (Jocelyn Falempe)

Merges:
- Backmerge drm-next for drm_panel and xe changes (Jani)
