++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.
