You received a tag, so if you decided to send v3, you need to include it.

+description: |
+  The Omnivision OV5693 is a high performance, 1/4-inch, 5 megapixel, CMOS
+  image sensor that delivers 2592x1944 at 30fps. It provides full-frame,
+  sub-sampled, and windowed 10-bit MIPI images in various formats via the
+  Serial Camera Control Bus (SCCB) interface.
+
+  OV5693 is controlled via I2C and two-wire Serial Camera Control Bus (SCCB).
+  The sensor output is available via CSI-2 serial data output (up to 2-lane).
