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.

Indeed this isn't even a frequency listed in the datasheet. Add support for 24MHz as well. The PLL settings result in slightly different link frequencies, so parameterise those.

Frame rates are obviously more restricted on 2 lanes, but some hardware simply hasn't wired more up.

IMX258 wasn't doing that as register 0x350 (FRM_LENGTH_CTL) switches it to a mode where frame length tracks coarse exposure time. Disable this mode and clip the range for V4L2_CID_EXPOSURE appropriately based on V4L2_CID_VBLANK.

Allow the pixel array to run with the normal settings, with the MIPI serialiser at half the rate. This requires some additional information for the link frequency to pixel rate function that needs to be added to the configuration tables.
