 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.

 60               The sensor supports either two-lane, or four-lane operation.

 62               For two-lane operation the property must be set to <1 2>.
