+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.
