Separate the timings for the DVP mode from the timings for the CSI-2 mode in the ov5640 modes definition. The CSI-2 timings will deviate from the DVP ones as the clock tree is calculated differently. In CSI-2 mode change the analog crop rectangles as the OV5640 pixel array is composed as: - vertically: 16 dummy columns, 2592 valid ones and 16 dummy columns for a total of 2624 columns - horizontally: 8 optical black lines, 6 dummy ones, 1944 valid and 6 dummies for a total of 1964 lines Adjust the analog crop rectangle in CSI-2 mode to: - Skip the first 16 dummy columns - Skip the first 14 black/dummy lines - Pass the whole valid pixel array size to the ISP for all modes except 1024x768, 720p and 1080p which are obtained by cropping the valid pixel array. Tested in RGB565, UYVY and RGB888 modes in CSI-2 mode.
