+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 either
+ - frame synchronization (Master: out-sync or Slave: in-sync)
+ - 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.
