This module has an OV5640 sensor connected via the parallel CSI interface, and an OV8865 sensor connected via MIPI CSI. I2C2 is the shared control interface for them. The active-low reset signal is shared by the two sensors, while each sensor has a dedicated shutdown line. The module's onboard regulator provide power for the OV5640, while the Bananapi M3 provides power from the PMIC for the OV8865. There's also a VM149C voice coil motor driver at I2C address 0x0c, and an unknown device responding on I2C address 0x20. Both are related to the OV8655 at address 0x36. Since there is no support for the OV8865, this patch only enables the OV5640.
