The patches were generated from the RPi repo with the following command: git format-patch v6.6.34..rpi-6.1.y Some patches needed rebasing and, as usual, the applied and reverted, wireless drivers, Github workflows, READMEs and defconfigs patches were removed.

Subject: [PATCH 0905/1085] drm/v3d: Enable V3D to use different PAGE_SIZE
|

Currently, the V3D driver uses PAGE_SHIFT over the assumption that
|
|
PAGE_SHIFT = 12, as the PAGE_SIZE = 4KB. But, the RPi 5 is using
|
|
PAGE_SIZE = 16KB, so the MMU PAGE_SHIFT is different than the system's
|
|
PAGE_SHIFT.
|
|
|
|
Enable V3D to be used in system's with any PAGE_SIZE by making sure that
|
|
everything MMU-related uses the MMU page shift.
