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 0445/1085] media: i2c: imx258: Make image geometry meet sensor
|
||
requirements
|
||
MIME-Version: 1.0
|
||
Content-Type: text/plain; charset=UTF-8

Content-Transfer-Encoding: 8bit
|
||
|
||
The output image is defined as being 4208x3118 pixels in size.
|
||
Y_ADD_STA register was set to 0, and Y_ADD_END to 3118, giving
|
||
3119 lines total.
|
||
|
||
The datasheet lists a requirement for Y_ADD_STA to be a multiple
|
||
of a power of 2 depending on binning/scaling mode (2 for full pixel,
|
||
4 for x2-bin/scale, 8 for (x2-bin)+(x2-subsample) or x4-bin, or 16
|
||
for (x4-bin)+(x2-subsample)).
|
||
(Y_ADD_END – Y_ADD_STA + 1) also has to be a similar power of 2.
|
||
|
||
The current configuration for the full res modes breaks that second
|
||
requirement, and we can't increase Y_ADD_STA to 1 to retain exactly
|
||
the same field of view as that then breaks the first requirement.
|
||
For the binned modes, they are worse off as 3118 is not a multiple of
|
||
4.
|
||
|
||
Increase the main mode to 4208x3120 so that it is the same FOV as the
|
||
binned modes, with Y_ADD_STA at 0.
|
||
Fix Y_ADD_STA and Y_ADD_END for the binned modes so that they meet the
|
||
sensor requirements.
|
||
|
||
This does change the Bayer order as the default configuration is for
|
||
H&V flips to be enabled, so readout is from Y_STA_END to Y_ADD_STA,
|
||
and this patch has changed Y_STA_END.
