This latest PR builds off prior rounds of work for Linux 5.18 including DG2-G12 platform support , Alder Lake N support , performance improvements for DG2/Alchemist , and other changes.
This latest (and likely last feature pull of i915 for v5.18) has a lot of display-related work. There are display IPS fixes, DP 128b/132b updates, a "major display code clean-up" while working to fix up the DisplayPort DFP 4:2:0 handling, big joiner updates, fixes for the DG2/Alchemist display code, and more. There are also Panel Self Refresh PSR2 fixes, Alder Lake P PHY fixes, PCH support for Alder Lake N, and other low-level changes.
