Subject: media: ov5640: Adjust format to bpp in s_fmt Author: Jacopo Mondi <[email protected]> Date: Fri May 13 15:14:14 2022 +0100 The ov5640 driver supports different sizes for different mbus_codes. In particular: - 8bpp modes: high resolution sizes (>= 1280x720) - 16bpp modes: all sizes - 24bpp modes: low resolutions sizes (< 1280x720) Adjust the image sizes according to the above constraints.
