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 0335/1085] drivers: bcm2835_unicam: Disable trigger mode
|
|
operation
|
|
|
|
On a Pi3 B/B+ platform the imx219 sensor frequently generates a single corrupt
|
|
frame when the sensor first starts. This can either be a missing line, or
|
|
invalid samples within the line. This only occurrs using the Unicam kernel
|
|
driver.
|
|
|
|
Disabling trigger mode elimiates this corruption. Since trigger mode is a
|
|
legacy feature copied from the firmware driver and not expected to be needed,
|
|
remove it. Tested on the Raspberry Pi cameras and shows no ill effects.
