description:
  OV9282 sensor is an OmniVision black & white CMOS active pixel digital image
  sensor with an active array size of 1296H x 816V. It is programmable through
  I2C interface. The I2C client address is fixed to 0x60/0x70 as per sensor data
  sheet. Image data is sent through MIPI CSI-2.
