+description: |
+ The Omnivision OV5693 is a high performance, 1/4-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.
+
+ Supports images sizes: 5 Mpixel, EIS1080p, 1080p, 720p, VGA, QVGA
+
+ OV5693 is programmable through I2C and two-wire Serial Camera Control Bus (SCCB).
+ The sensor output is available via CSI-2 serial data output (up to 2-lane).
