+description: |-
+ The Arducam 1/1.7-Inch 64Mpixel CMOS active pixel digital image sensor
+ with an active array size of 9248 x 6944. It is programmable through
+ I2C interface. The I2C address is fixed to 0x1A as per sensor data sheet.
+ Image data is sent through MIPI CSI-2, which can be configured for operation
+ with either 2 or 4 data lanes.
