description: |-
  The STMicroelectronics VD1943 is a 5.1 M combined global shutter and rolling
  shutter image sensor with an active array size of 2560 x 1984. It is
  programmable through I2C, the address is fixed to 0x20. The sensor output is
  available via CSI-2, which is configured as either 2 or 4 data lanes. The
  sensor provides 4 GPIOS that can be used for either :
    - frame synchronization (Follower mode: in-sync)
    - external LED signal (synchronized with sensor integration periods)
