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 0238/1085] media: bcm2835-unicam: Always service interrupts
|
|
|
|
From when bringing up the driver, there was a check in the isr
|
|
to ignore interrupts (claiming them handled) should the driver
|
|
not be streaming.
|
|
|
|
The VPU now will not register a camera driver if it finds a
|
|
CSI2 node enabled in device tree, therefore this flawed check is
|
|
redundant.
