I3C busses have to know about all I2C devices connected on the I3C bus to properly initialize the I3C master, and I2C frames can't be sent on the bus until this initialization is done. We can't let the I2C core parse the DT and instantiate I2C devices as part of its i2c_add_adapter() procedure because, when done this way, I2C devices are directly registered to the device-model and might be attached to drivers which could in turn start sending frames on the bus, which won't work since, as said above, the bus is not yet initialized. Export of_i2c_register_device() in order to let the I3C core parse the I2C device nodes by itself and initialize the bus.

README
Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
See Documentation/00-INDEX for a list of what is contained in each file.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
