+description: |-
+  The Sony IMX708 is a 1/2.3-inch CMOS active pixel digital image sensor
+  with an active array size of 4608H x 2592V. 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.
