+description: |-
+  The Sony IMX296 is a 1/2.9-Inch active pixel type CMOS Solid-state image
+  sensor with square pixel array and 1.58 M effective pixels. This chip
+  features a global shutter with variable charge-integration time. It is
+  programmable through I2C and 4-wire interfaces. The sensor output is
+  available via CSI-2 serial data output (1 Lane).
