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 0784/1085] media: rp1: cfe: Improve link validation for
|
|
metadata
|
|
|
|
Improve the link validation for metadata by:
|
|
- Allowing capture buffers that are larger than the incoming frame
|
|
(instead of requiring exact match).
|
|
|
|
- Instead of assuming that a metadata unit ("pixel") is 8 bits, use
|
|
find_format_by_code() to get the format and use the bit depth from
|
|
there. E.g. bit depth for RAW10 metadata will be 10 bits, when we
|
|
move to the upstream metadata formats.
