+Description:
+ I3C’s Hot-Join mechanism allows an I3C Device to inform the
+ Active Controller that a newly-joined Target is present on the
+ I3C Bus and is ready to receive a Dynamic Address, in order to
+ become fully functional on the Bus. Hot-Join is used when the
+ Target is mounted on the same I3C bus and remains depowered
+ until needed or until the Target is physically inserted into the
+ I3C bus
+
+ This entry allows to enable or disable Hot-join of the Current
+ Controller driving the bus.
