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 0427/1085] drivers: media: i2c: imx708: Fix WIDE_DYNAMIC_RANGE
|
|
control with long exposure
|
|
|
|
Setting V4L2_CID_WIDE_DYNAMIC_RANGE was causing the long exposure
|
|
shift count to be reset, which is incorrect if the user has already
|
|
changed the frame length to cause it to have a non-zero value.
|
|
|
|
Because it only updates control ranges and doesn't set any registers,
|
|
the control can also be applied when the sensor is not powered on.
