+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)
+

+ - st,st-vd56g3
+ - st,st-vd66gy
+ description:
+ Two variants are availables; VD56G3 is a monochrome sensor while VD66GY
+ is a colour variant.
