12description: |
13  The Omnivision OV4689 is a high performance, 1/3-inch, 4 megapixel
14  image sensor. Ihis chip supports high frame rate speeds up to 90 fps
15  at 2688x1520 resolution. It is programmable through an I2C
16  interface, and sensor output is sent via 1/2/4 lane MIPI CSI-2
17  connection.
