+description: |-
+  The Sony imx219 is a 1/4.0-inch CMOS active pixel digital image sensor
+  with an active array size of 3280H x 2464V. It is programmable through
+  I2C interface. The I2C address is fixed to 0x10 as per sensor data sheet.
+  Image data is sent through MIPI CSI-2, which is configured as either 2 or
+  4 data lanes.
