  37 +description: |-
  38 +  The Sony imx219 is a 1/4.0-inch CMOS active pixel digital image sensor
  39 +  with an active array size of 3280H x 2464V. It is programmable through
  40 +  I2C interface. The I2C address is fixed to 0x10 as per sensor data sheet.
  41 +  Image data is sent through MIPI CSI-2, which is configured as either 2 or
  42 +  4 data lanes.
