It is set using one of the following macros defined in the driver: #define IMX258_VTS_30FPS 0x0c98 #define IMX258_VTS_30FPS_2K 0x0638 #define IMX258_VTS_30FPS_VGA 0x034c There's a clear mismatch in the value for the full resolution mode i.e. IMX258_VTS_30FPS. Fix it by rectifying the macro with the value set for the frame_length_lines register as stated above.
