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 0010/1085] drm/vc4: hvs: Force modeset on gamma lut change
|
|
|
|
The HVS Gamma block can only be updated when idle, so we need to disable
|
|
the HVS channel when the gamma property is set in an atomic commit.
|
|
|
|
Since the pixelvalve cannot have its assigned channel halted without
|
|
stalling unless it's disabled as well, in our case that means forcing a
|
|
full disable / enable cycle on the pipeline.
