+description: |
+  The Omnivision OV4689 is a high performance, 1/3-inch, 4 megapixel
+  image sensor. Ihis chip supports high frame rate speeds up to 90 fps
+  at 2688x1520 resolution. It is programmable through an I2C
+  interface, and sensor output is sent via 1/2/4 lane MIPI CSI-2
+  connection.
