14 The Omnivision OV8856 is a high performance, 1/4-inch, 8 megapixel, CMOS
15 image sensor that delivers 3264x2448 at 30fps. It provides full-frame,
16 sub-sampled, and windowed 10-bit MIPI images in various formats via the
17 Serial Camera Control Bus (SCCB) interface. This chip is programmable
18 through I2C and two-wire SCCB. The sensor output is available via CSI-2
19 serial data output (up to 4-lane).
