description: |
  The Omnivision OV5675 is a high performance, 1/5-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.

  This chip is programmable through I2C and two-wire SCCB. The sensor output
  is available via CSI-2 serial data output (up to 2-lane).
