When the kernel starts up, it kicks off compiled-in drivers that match “compatible” entries it finds in the device tree. At a later stage (when /lib/modules is available), all kernel modules that match “compatible” entries in the device tree are loaded.
But if there is no dt table then there should be a fall back path with which desired kernel modules can be loaded. Hence, add of_device_id table in the i2c driver to be able to use when there is no dt table.
