Subject: media: ov5640: Implement get_selection Author: Jacopo Mondi <[email protected]> Date: Fri May 13 15:14:09 2022 +0100 Implement the get_selection pad operation for the OV5640 sensor driver. The supported targets report the sensor's native size, the active pixel array size and the analog crop rectangle from which the image is produced.
