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 0590/1085] drm/vc4: hvs: Create hw_init function
|
|
|
|
Since the BCM2712 will feature a significantly different HVS, let's move
|
|
the hardware initialisation part of our bind function into a separate
|
|
function.
|
|
|
|
That way, it will be easier to extend in the future.
