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 0663/1085] media: i2c: ov9282: Read chip ID via 2 reads
|
|
|
|
Vision Components have made an OV9281 module which blocks reading
|
|
back the majority of registers to comply with NDAs, and in doing
|
|
so doesn't allow auto-increment register reading as used when
|
|
reading the chip ID.
|
|
|
|
Use two reads and manually combine the results.
