+description: |-
+ The Sony IMX378 is a 1/2.3-inch CMOS active pixel digital image sensor
+ with an active array size of 4056H x 3040V. 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 is configured as either 2 or
+ 4 data lanes.
