[v2,00/27] Enable Lunar Lake display

Message

Cross posting this to the i915 and xe mailing lists. The basic platform
enabling for Lunar Lake is already applied in the xe driver[1].
This patch series adds the display support in the i915 driver, that is
going to be shared with xe.

Differently than v1, this v2 is based off drm-intel-next so we can start
applying the patches. Since drm-xe-next is now much closer to
drm-intel-next, the patches apply cleanly there too.

Another difference from v1 is that the prerequisite patches are all
applied already, so we can drop them from this series. Also dropped from
the series is the final patch to xe driver enabling the display, since
that doesn't apply to drm-intel-next.

I went a few times through all the review comments and adapt the patches
according to what we discussed. The main things missing are the patches
marked with "FIXME:". Those are because they depend on the different
approach I implemented for "drm/i915/xe2lpd: Move registers to PICA".
Once that is agreed upon, I can go back and adapt these patches.
