89	  This is for setting up I3C controller device driver instance
90	  and also to perform bus initialization (e.g. dynamic address
91	  assignment).
92
93	  Note that this needs to be done before the device driver
94	  instances of the connected I2C and I3C devices start
95	  initializing those devices. This is because some devices
96	  may not be addressable until addresses are assigned by
97	  the controller.
