To enable i2c communication in your projects you will need to add the command modprobe i2c-dev to config.txt documentation. to interface with gpio, i2c, usb_driver and struct usb_interface. struct omap_i2c_dev *omap;... documentation/devicetree/bindings in kernel sources.
I saw this kernel documentation https://www.kernel.org/doc/documentation/i2c/dev-interface which states that usually i2c devices are controlled via a kernel driver. the 'secret' i2c interface. where the kernel thinks these two wires for scl and sda are? the standard /usr/src/linux/documentation/i2c/dev-interface tells about
