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 0236/1085] media: bcm2835-unicam: Drop WARN on uing direct
|
|
cache alias
|
|
|
|
Pi 0&1 pass all ARM accesses through the VPU L2 cache, therefore
|
|
the dma-ranges property sets the cache alias bits to other
|
|
than the direct alias, hence this WARN was firing.
|
|
|
|
It was overprotective coding, so assume that everything is OK
|
|
with the dma-ranges, and remove the WARN.
