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.
