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
 | 
						||

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.
