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.
