 14description: |-
 15 The STMicroelectronics VD55G1 is a global shutter image sensor with an active
 16 array size of 804H x 704V. It is programmable through I2C interface. The I2C
 17 address is fixed to 0x10.
 18
 19 Image data is sent through MIPI CSI-2, which is configured as only 1 data
 20 lane. The sensor provides 4 GPIOS that can be used for external LED signal
 21 (synchronized with sensor integration periods).
