description: |-

 The STMicroelectronics VD55G1 is a global shutter image sensor with an active

 array size of 804H x 704V. It is programmable through I2C interface. The I2C

 address is fixed to 0x10.

 Image data is sent through MIPI CSI-2, which is configured as only 1 data

 lane. The sensor provides 4 GPIOS that can be used for external LED signal

 (synchronized with sensor integration periods).
