+description: |-
+  The STMicroelectronics VD56G3 is a 1.5 M pixel global shutter image sensor
+  with an active array size of 1124 x 1364 (portrait orientation). It is
+  programmable through I2C, the address is fixed to 0x10. The sensor output is
+  available via CSI-2, which is configured as either 1 or 2 data lanes. The
+  sensor provides 8 GPIOS that can be used for external LED signal
+  (synchronized with sensor integration periods)
