 12description:
 13  The OmniVision OV2735 is a 2MP (1920x1080) color CMOS image sensor controlled
 14  through an I2C-compatible SCCB bus. it outputs RAW10 format and uses a 1/2.7"
 15  optical format.

 44      Active-low enable pin. Labeled as 'PWDN' in the datasheet, but acts as
 45      an enable signal. During power rail ramp-up, the device remains powered
 46      down. Once power rails are stable, pulling this pin low powers on the
 47      device.
