  12 description: |
  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.
