Because not all I3C drivers have the hot-join feature ready, and especially not all I3C devices support hot-join feature, exporting SETDASA method could be useful. With this function, the I3C controller could perform a DAA to I3C devices when users decide to turn these I3C devices off and on again during run-time. Tested: This change has been tested with turnning off an I3C device and turning on it again during run-time. The device driver calls SETDASA method to perform DAA to the device. And communication between I3C controller and device is set up again correctly.

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.
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.
