  12 description: |-
  13   The Sony imx219 is a 1/4.0-inch CMOS active pixel digital image sensor
  14   with an active array size of 3280H x 2464V. It is programmable through
  15   I2C interface. The I2C address is fixed to 0x10 as per sensor data sheet.
  16   Image data is sent through MIPI CSI-2, which is configured as either 2 or
  17   4 data lanes.
