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 0135/1085] media: tc358743: Increase FIFO level to 374.
|
|
|
|
The existing fixed value of 16 worked for UYVY 720P60 over
|
|
2 lanes at 594MHz, or UYVY 1080P60 over 4 lanes. (RGB888
|
|
1080P60 needs 6 lanes at 594MHz).
|
|
It doesn't allow for lower resolutions to work as the FIFO
|
|
underflows.
|
|
|
|
374 is required for 1080P24-30 UYVY over 2 lanes @ 972Mbit/s, but
|
|
>374 means that the FIFO underflows on 1080P50 UYVY over 2 lanes
|
|
@ 972Mbit/s.
